Most people are here to complain about pronunciations. I'm here to thank you so much for setting up this procedure!
Gary now is anEnglish teacher, that made my mind blow. Thanks :)
I profess, the Professor keeps professor-ing
I prefer to say router than router. The same way I prefer data instead of data.
Aladeen or aladeen?! XD
Router, Rooter data, daita tomato tomoto :)
Zach Sylvester its daita no dah tah
I can hear this comment.
Just out of spite I will now change the way I pronounce Routine and Roulette to be more in line with the way I say Router
Give it a rest. If Americans and British don't even pronounce the alphabet the same, why would you expect every word to be pronounced the same.
If you move to Canada you may also need to change the way you pronounce poutine.
Blasphemy! Burn the heretic
I'm Aussie and when it comes to the word router I say 'row-ter' as it seems rather impolite to say 'root-her'.
lol
If you're not root, you're not getting in!
Root her? I barely know her.
😂😂😂
OH ROOOOOOOOOOOOT HERRRRRRRRRR!! FUCK YEAH!
FINALLY! Somebody acknowledges that there are many ways to pronounce a word, it is just regional speech differences.
Question about raspberry pi Wi-Fi router. Can you have multiple access points on pi's Wi-Fi?
You can install the Openwrt system on a separate SD, which provide an all-in-one router solution.
That might make a good video. I will look into that.
Not on a PI 4. Afaik there is no official support for that device in the Linux kernel yet.
Oh, I might be wrong. There is a OpenWRT Snapshot with Raspberry Pi 4 support.
*Routine*
*Roulette*
Instant upvote.
Lol
How would you say outer?
Like the outer Lane?
The ooter lane?
Laughing
@@mspencerl87 I think the sound of the pronunciation requires the letter "R" before the "OU" , but then it makes me wonder if the British women enjoy sex on the roof or rough sex in the bed?

@@mattiviljanen8109
Bad example; begins with a 'P' and pou in a word is never pronouced poo.
So, how do you pronounce couch and count?
Wouldn't want to confuse root and route when working in Linux. Hence while learning I learned to pronounce route as raute.
ah, the consistency card. while I respect your right to do as you wish, I will continue to proudly pronounce a confoundingly loud "ou'" sound around the ploughed grounds of the grouted house of a mouse floundering in dousing his flaming trousers as his aroused spouse shouts about his clout.
oh crackle
btw how do you pronounce "route" as in "Route 66"? because thats basically where "router" comes from.
@@aaron9828 generally, I say "rowt" as a common noun, i.e. "I'll take the quickest rowt home,"
i say "root" as a proper noun, i.e. "I'll take Root 66"
I’m wounded.
Haha I feel your pain Brother!
Ahh yes, because words generally have consistant pronounciation in English lmao

pronoun vs pronun
That's a good idea with precisive instructions. Thank you very much.
You are welcome!
What is the throughput like when doing this? Also any chance of a video for 2 wireless adapters so 1 could get an address as a station and other could work as an AP? Would make for a neat travel router.
That is an interesting idea. I will put that in my tentative TODO list.
That would be great. Always better to have your own device. I've seen a setup using OpenWRT but would rather stick to this if possible.
I can't wait to make my pi rooter! You really are a lifesaver, thanks for the video!
GREAT video!!!
How hard would it be to add Wire Guard VPN to a remote Pi that would connect to the UniFi UDM-Pro with a VPN VLAN (Subnet 70)? This way everything that connects to the Pi would be directed to my home network (for local access) and its Internet connection for security reasons. I believe that I can figure out how to use 2 5GHz USB WiFi modems, one as an AP and one to connect to the Public IP for Internet service. The Pi's Ethernet port would also have access to my home network via Wire Guard This is my next project.
I'd be interested about the performance of the RPi as a router - like ping times or download / upload rates of things connected via the RPi. I'm using my linux PC as a router in much the same way as you're using the RPi there except with more ethernet ports added via PCIe - it's basically my own personal router plugged into my landlord's router. I should maybe see if my RPi can give me a lower energy option to keep my WiFi on when I don't need to use my PC. I'd be concerned that the RPi would be slower but if it's not a lot slower I could maybe have always on WiFi without burning too much energy. Thanks for the idea.
On another point, I don't see that routine and roulette say anything about how to pronounce router. Think of the pronunciation of the 'ough' in tough, though, through and thorough. English pronunciation simply isn't consistent even within one style of English (like British English or American English). I know that you didn't claim that anybody was right or wrong in their pronunciation of router, but maybe you could have stopped after acknowledging the difference and saying that you prefer to use the British style. There wasn't a need to try to justify it. It's comes across as making an attempt to persuade (aka an argument). I speak British English btw, so I say this despite naturally preferring your choice of pronunciation.
Lol I say it the American way and I’m Australian (which traditionally follows British English but the American cultural influence is so much stronger nowadays here I reckon).
It’s also one of those words though that tend to follow industry-language as opposed to cultural language. A lot of our networking education is US company Cisco-made too.
OMFG, this video was needed. There are dozens of tutorials telling you how to ssh over a network or over ethernet using fixed IP, cause duh. This is the only one that offers a straightforward solution for a routerless ssh connection to the pi over wifi. This is HUGE for DIY-pi in the field. Thanks for the super clear markdown notebook. I seriously don't know how to upvote this enough, I had not found hostapd on my own. THANK YOU.
G'day from Australia, Gary. Ya mad rooter!
Network topology diagrams - what did you use Gary to draw yours?
Also does anyone else know of one that can be used across iPad/macOS and maybe iOS? Even if it’s web-based.
Cheers
A strange thing; I was messing around with an old netbook (on which I'm running Debian, sans GUI, naturally) and I managed to get it to share its internet with my Windows laptop with relative ease. (Said netbook connected to wireless network, and to Windows machine via an ethernet crossover cable.)
Tried replicating the process with a Raspberry Pi, and I just can't get it to work. Despite it being (more or less) the same OS. Hopefully your commands list will give me some hints.
Thanks for the video!
I have a question, is it possible to create a mesh node network with multiple transmitters and receivers? So that you can things back to a cloud network? say for example if I wanted to track a fleet of trucks
Hi Gary, Am i able to use this to connect to smart devices? and if so can I add more pi's to act as an Access Point?

You are missing a sudo for "iptables-restore < /etc/iptables.ipv4.nat" in your documentation.
Hi from México, it can be use as a router-firewall or install pfsense firewall in a raspberry Pi 4 , thanks
Thanks!
I'm looking to upgrade my all in one Fibre router/modem that I have from my ISP in UK could you recommend any to have gigabit ports & decent WiFi ?
I'm assuming it's not a good idea to turn a raspberry pi into the main router/modem? Even if that's possible... Cheers
Good video Gary. Just one question, you thumbnail shows two Ethernet leads (one yellow and one blue) but the RPi4 only has one Ethernet port. Where does the second lead plug in to the RPi4?
I guess you weren't paying much attention to the video!!! 😂 See 1:58
@@GaryExplains ah thanks, I must have been distracted by the router pronunciation nonsense.
Amazing video Gary! Loved it.
It need a 4 way network switch hat to will fit the Raspberry Pi or possibly using the UDOO RYZEN Bolt V8 as it is more powerful than the Raspberry Pi you will also need a WAN port and is there such a thing as a WAN Hat for the Raspberry Pi.
Great video, just followed the instructions and everything worked for me.
Hi Gary, I also hope that you can do a tutorial on how to setup a good open source router software with graphical interface on rpi
Thanks for the video
Hi! Is there a way I can use my RPi4 in a "reversed" way? I want to receive my existing WiFi signal in my Pi (from my wireless router i have downstairs) and route it through the Ethernet port of the Pi, so I can plug it another router, wich is upstairs. I don't want to bring a cable from downstairs to upstairs and I really need to use this router, because I want to use it's USB 3.0 port for network file sharing. Thank you!
Great Gary video .
Been using PI4 + VLAN switch as main router for a few months - very versatile.
Configure iptables to block external access.
Added Docker + pihole for ad block filter
Docker + samba for file share
Docker + vnstat for traffic counting
Docker + smokeping for uptime
I guess one might even be able to compile PfSense and run it on the Raspberry Pi.
They say router in a certain way because of the way they say route. A router routes network traffic. A satellite navigator creates a route, or changes route based on the route taken.
Exactly and the British say route as I say router! 🤷♂️
Great video, thank you . I was able to use the eth1 but the wifi network although visible would not work with my other devices. Meaning : the devices would see the Wifi network but would be “unable to connect to XXX” I tried this with PCs iPhones Macs abs wouldn’t work. Any ideas ? It seems like a problem with authentication or something else. Your help is appreciated !
Really enjoyed doing this small project
I will be short and straightforward:
Is it possible to protect (other PCs that are connected to the internet through the pi) if the pi has a firewall, antivirus or any other sort of protection? Just curious since I'm currently using a pi as a router and it also has a firewall set up.
Other than that... great video as always.
Id like to know as well. Assuming you installed/enabled ufw on your pi router, does that protect the Pi's network? I will try it out, I have a spare hub and will comment on how I can validate this.
@@reyarqueza7627 Well, I can answer to my own question right now:
Yes, (whatever is connected to the pi with firewall, etc) will benefit from the additional security.
@@GustavoMsTrashCan Thank you for verifying that! I look forward to building this out in my cave soon.
Question: How can I access devices on the eth1 from the eth0 network?
Is there a way to make a raspberry pi handle the modem part as well.. i mean make it modem/router?
Thanks!
@TerraTN thanks for the answer. to my knowledge, we dont have to do such thing. I can by any adsl2+ modem and plug it to the network and it runs with no registration.. i only have to configure it to our ISP and added the login values.
The wifi access point couldn’t be authenticated . I did everything as per the instructions. I did do a few reboot and a reinstalls
Thoughts ?
So is it possible to connect your raspberry pi to a public WiFi, and then connect a switch to the Pi4 Ethernet port? I have to pay for internet in my dorm, but can only connect 3 devices to the wifi, and have to list the Mac address of each device on my account(Boingo internet at a military installation)
Hi Dear, is it possible to configure the Pi as a FireWall ?... thanks
Nice video, thanks!
Any chance I could get the detailed instructions? They don't seem to be at the github link.
The instructions I have written on GitHub are fairly detailed. What seems to missing or not clear?
Can you use an ethernet switch instead and connect both WAN and LAN, or even multi WAN?
Afaik, you only need one physical port. In the late 90ies, I had a modem and a network-card in the main PC, and used it as Router. A switch was connected to the NC and the modem on the COM-Port.
For routing, (Route66 is pronounced like root, isn't it?), I connected the eth0-Port twice:
sudo ifconfig eth0:1 192.168.2.1 up
sudo ifconfig eth0:0 192.168.3.2 up
This year, I will try it with the Raspi and WLAN, since my mother doesn't have Internet connection, but there is a public hotspot nearby. Maybe I can connect not only the Pi, but my Laptop, the Smartphone and the equipment of my sister to it. :)
Well, since the hotspot only serves 2h of internet per day per User (maybe identifying by HW-addr., maybe by cookies - didn't find out by now), I will probably use an UMTS-Stick for uplink, additionally.
May I ask, what Ethernet adapter was used in this video?
i dont get it, if you need a separate network, put it in a different vlan and set rules to separate it, or am i missing something here ? whats the benefit in doing whats shown in the video ?
Thanks for this video, I'm looking for a way to seperate my IoT devices from my other devices.
I watch a lot of BritBox so I can switch between English-English and American-English. Now Scottish-English is another language all together. I watched "Still Game" and didn't understand one word Isa said during the entire series!
Is it possible to have same subnet for eth1 (to LAN devices) and wlan0 while eth0 is connected to router?
What do I need to change in order to use a phone tethered via usb to my raspberry pi 4? I followed the setup connected through eth0 from my standard router and it worked great, omitting eth1 because I don't have a need for it. Now I want to configure it to use my phone's data. I can connect to the internet through my phone on the raspberry pi itself, but my devices connected to the pi's wifi don't get internet access.
Making it a pi hole would have been better anyways I would love to see a follow up where u turn it into a pi hole and solve 2 problems with a single device
Yes I agree, I think a video just about Pi Hole is probably worth doing.
Appreciate it a lot
Add docker + pihole in a container.
Disable dnsmasq and run container with --net=host --cap-add=NET_ADMIN and use pihole for Ad Block + DNS + DHCP.
@@GaryExplains pihole ( ͡° ͜ʖ ͡°)
with vlan you dont even need a second adapter. Openwrt is the way to go if you want a router.
Hi Gary! Ufw is blocking all forwarding traffic. May you explain how to configure it correctly? Thanks
rooting for this vid, but i can't stop imagining packets with roots. Should't it be called a planter then?

Hi sir,
May I know if it is possible to use raspberry pi for Mikrotek? We want to provide wifi hotspot in our area. Using creadentials login/guest. AP Hotspot provider.
Thanks,

Can you install this router functionality in a VM running on Raspberry Pi 4? Or in other words, can Raspberry Pi be used to serve multiple functions via one eth0 port? Eg one VM does the routing, another VM is used for containers, and maybe another VM is running Linux in the cloud.
Will your Home network know to route to your new subnet? If so how
Can I have the raspberry pi WIFI hotspot broadcasting in 5 GHz (hw_mode=a) and 2.4 GHz (hw_mode=g) at the same time?
What usb-Ethernet adapters are supported by Pi OS?
that's kind of what i want to do. ideally i wanted to be able to add a hat of some description to give me 4 gig lans so i could skip having to use a switch. unfortunately i couldn't find one. im in two minds about scaling down what i want to do and doing what you said in this vid, or putting together a small pc and putting a nic with 4 gig ports on it which would require more power, but i could do a lot more and have the option to add more 4 port gig lan cards, which would be nice, not that i need that at present. though i can see a need for it if i fully network the house the way i'm concidering.
2:35 thank you for being honest... And not saying instructions below and not having the instructions below but in another web page that may or may not be working
You actually said the truth instructions on another web page thank you
I honestly hate UA-cam videos that say instructions below when the instructions are nowhere to be found but they are possibly on a web page that is linked and maybe being maintained or not aka 404 it is extremely frustrating
A route (rowt) is what happened at the Boston Tea Party. A route (root) is the way to get from A to B
i did that configs around 5 years ago with RPI 2 B. So great solution and is working yet
and with shorewall firewall is go so good, more safe with a pihole configs too
Would these steps be the same for orange pi 4?
@Gary Explains
So generally, how does a pi 4 router compare against a 64bit x86 router. I get that there are lots of "it depends" but I'm just looking for a general guid. I would like the low power of a pi, but my 64bit x86 quad core is quite low in latency and fairly high throughput.
How do you say route? I say route differently than roulette and routine. route-r.
I actually like this pronunciation. Whenever I explain what a "router" does I tell people it should be called a "route her " that is if you want to think of a packet as a "her". His pronunciation pretty much says what it does.
Hello is it possible that raspberry pi controls the bandwidth limitation to the devices connected to it?
Yes, the tool you need to use is "wondershaper".
@@GaryExplains thanks, will definitely try it.
In English we have both pronunciations of Router. The one that "Gary Explains" sounds like Rooter and is used to Route (Root) network traffic and then there''s Router that is pronounced just like they do in the States but it takes a quarter inch bit and is used for shaping wood!
*Deeper Connect Mini* is the world’s first Decentralized Private Network (DPN). Your Internet connection becomes untraceable, unstoppable, and without data leakages or the loss of Internet speed you usually experience on VPNs. It is also plug and play, since it does not require any configuration.
I have followed instructions and my pi works! However after 12 hours my network on the pi cannot be found and all my devices can not connect. I think the lease might not be renewing?
Hi Gary
I configured the WiFi. It works fine until I connect to VPN server. I get no internet connection over the WiFi. I use OpenVPN to connect to remote server. Any idea what is wrong with the configuration?
I'm getting "failed to initialize nft: protocol not supoorted" after the command "sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE"
Edit- fixed with a whole system reboot.
But I also have a complex issue I was hoping I could ask you about.
Very well done. I had to attend college and receive a degree before the business world accept my knowledge of networking. Then they masked the reason for not hiring me, due to age, by telling me I had too much experience. Pooh.
Has anyone tried this and then used it to run a steamlink setup?
would the 5ghz wifi AP run video data to run at least 720p video at 60fps?
You are correct about how we say “routine” and such, but router is based on the word “route”.
Here in America, most people I talk to say “raut”, not “root”. This is why we say “rauter”.
I know there are idiots out there who will make fun of you for saying things differently, but that doesn’t mean you have to stoop to their level and make assumptions
I didn't make any assumptions. I know fully well that American's pronounce router that way because it is from the verb "to route" and that is how they pronounce "to route". In fact multiple times I have replied to people here who have said that Americans get to name a router as "a router" because they invented it, to which my reply is that they didn't invent the verb "to route".
Just burn a openwrt image on it and your done. Make sure the openwrt image have drivers for that usb eternet this can be done using image builder.
As I mentioned to someone else, a separate video on OpenWRT on Pi might be worth doing.
Where did you get such large yellow cables? 😅
Hi pal
Like to First Thank you so much for this guide
I have set up as Detailed instructions stats
I have done a speed test on eth1 and wlan0
And it seens like eth1 is not getting the same or more speed
as wlan0
eth1 is getting 4Mbps
wlan0 is getting 20Mbps
On the RpI is getting 20Mbps
Any Way on to fix this?
Why would you make another network for your gaming anyway? What's the _benefit_ of doing that? Are there any downsides? I'm not interested in a _how to_ unless it makes stuff _better._ So how is this making home gaming better? I can see how this _might_ be better for LAN gaming, but by the looks of things I'm not convinced that this is better for online gaming due to the extra step needed.
I haven't re-watched the video to see exactly what I said, but my guess would be that I was referring to LAN gaming, not online gaming.
@@GaryExplains Thank you for your reply! I've been looking for ways to replace the regular router of my home, but I'm currently unsure if my ISP will even let me lol.
Interesting exercise, but most of that could be done by adding a flea market rooter that will require lots less attention at a fraction of the price. Suspishus about the throoput of the USB/Ethernet adapter as well. (Please note proper Canadian compromise spellings).
Can the raspberry pi router work without the connection of my router?
if you are using Ubuntu, creating a wifi hotspot network is just a few clicks away
Can I use Rpi to replace my router that connects to internet using PPPoE?
Does that mean you pronounce oot instead of out? Or mooth instead of mouth?
How do you pronounce routine?
You make an interesting point about the pronunciation of Router. However in the context of IT security saying Router the way the British say it, really makes it difficult for people to tell the difference between a router and a rooter, which would be something that roots a device. Just saying, the American English pronunciation may have certain pragmatic motivations you may not have considered. Consider the way that the following sentences sound in British and American English:
You need to be root if you want to change the routes. What routes are open to the root account on the router?
That is all very interesting and might even be a valid argument if American English has no homophones, but it does: It would be a great feat if I could alter the altar with my feet.
I was in awe when I saw the oar, or was I in awe when I saw the ore?
Why cant i ignore the whole eth1 interface on the whole. I wanted it to get a dynamic IP from ISP and be an AP to transmit them via WIFI. Just like a normal router does.. I'm not going to connect any device via ethernet interface. Any solutions will be helpful
Probably would have been worth mentioning that you would have to add a static route on the internet router to point back to the raspberry pi's eth0 interface for the extra networks, otherwise the internet will not work on those networks as the internet router would not know how to get back to the 192.168.7.x network in your example.
Even after that it may not work at all as a lot of home routers will not NAT an ip address that is not on its local subnet, so you would have to perform NAT on the raspberry pi aswell
I am not sure about that. It worked for me. I think the "sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" handles all the necessary network address translation.
It seems like it is doing NAT then as it is in the command, this would also negate the need for a static route on the internet router 👍
Can pi4 supports 802.11ax? If not how can I make ax supported
I am watching this with automatic subtitles and every time he says "router" Google writes "ROOTER".
While we’re at, is the eighth letter of the English alphabet aitch or haitch?
Either, depends on your local accent. In London it is predominantly haitch.
I'd like to connect a 4G dongle and build a portable router, but I'm concerned things will breach in. Could you explain some fundamental security layers?
man, that thing with powerbank + solar cell + someone free wifi do sell with high price as vpn/proxy.
It is a great way to learn network routing. But anyone can buy a proper router for ther price of Pi & ethernet adapter. That would also provide more coverage on WiFi & more ethernet ports.
The PI4 is much more versatile proper "dumb" router.
Thanks so much for putting this together! It's been by far the clearest explainer I've seen.
take my like just
for the router/ ruter explanation
I’am confused, should i say water or water ?
