    I have been looking at UA-cam videos for days now, learning about subnets, VLANs, managed switches, security and firewall rules, and bunch of other related details. I have to tell you - YOUR approach is top notch. You make a clear presentation, you make it understandable, and you never launched into unnecessary details.
    Your work gives me the confidence I needed in order to start making actual changes to improve my home network.
    Thank you!

    I understand that you can free up network IPs by using variable length subnet masking. But it has to be only used when you need many private networks and less hosts within the private domain range. In the latter case, which is a SOHO application, you can use different subnets with the default masking. Then, you can route from one subnet to the other and configure ACLs.

    • @PE4Doers
      @PE4Doers  Рік тому +1

      That is true, however when you have a group of high-traffic devices that communicate mostly between themselves (that also use broadcast to all often), and you has some critical devices that you do not want to have to even see that traffic, then subnets are a great advantage.

      Fir the transient PC's and the moil devices that would be no problem. However, when you have ANY servers or network equipment all Wireless, that tends to be more error prone unless it is an extremely simple network. It may work 98% of the time, but when you run into a problem it will drive you crazy - especially if the main router is only accessed witlessly.

    • @PE4Doers
      @PE4Doers  2 роки тому +2

      As I show in the bit map. the 24th bit flips the second half of the 512 address octet from .30 to .31 when that bit is set to one. What is important to follow there is that the 3rd octet is split, with the first 7 bits being part of the network address range and the 8th bit being part of the host address range. It is something only encountered in a home/small office environment (like mine) where 510 addresses are needed rather than the usual 254 provide by a Class-C range.

    Subnets is the only option if you have old routers. VLAN is preferred especially if you have managed switches.

    • @PE4Doers
      @PE4Doers  Рік тому

      I 'sort of' agree, since it it not really "Old" Routers as much as it is Consumer Routers rather than Pro-Sumer equipment.
      VLANS are fantastic for the larger implementations of a Home/Home-Office setup, and I will soon be implementing one my self in the very near future.
      However, the concept is not very user-friendly to non-network engineers trying to implement a fully featured configuration for Home/Home-Office configurations. It take a fairly knowledgeable individual to set one up who has not al least studied for a Network Admin credential.
      When I make the transition to Pro-Sumer equipment I plan on carefully crafting my video series so that other would have a chance of mimicking what I have done. It is VERY frustrating for someone outside our tight niche of advanced networking to buy equipment that is very difficult (if not impossible) to get working without hiring someone to fix everything for them. Even then, the network security of a third-party configured network setup would always be subject to security issues.

So here the situation, I'm sure that all cables will converge into a small room, and a few rooms in the house will have only one ethernet jack outlet per room. I know I will have a switch to manage all connections in the "network" small room, but since I will only have one ethernet jack in a room where I need more than one device needing a connection, can I set up another switch to connect a few devices? Is this possible without degrading the connection? Thank you.

    • @PE4Doers
      @PE4Doers  Рік тому

      It might, however it could have the reverse affect due to increased complexity.
      For example, wearing a second pair of socks on your boot-covered feet might keep more of the chill out, however, it could reduce the friction of the boot to your feet and you could lose a boot in heavy snow. I only mean to say that the extra layers of complexity could have unforeseen consequences.
      In your scenario, it might lead to someone being able to more easily attain Admin access to both devices if you use the same password for both, then, after they penetrate the first they can gain insight into how the second is configured, and that is one of many things to consider.
      I like keep things simple and easy to monitor, so I would always use one and monitor it very carefully. The trick will always be to limit any connections being allowed into your network.
      Maybe in a follow-up video I can show some secure ways to transfer information between your internal network and a device on the internet - if I get enough interest in that.

    So when you're setting up a static IP address, do you also use the subnet mask of 255.255.254.0 on the electronic component? Such as another computer or switch? I see that you're not setting up static IP address through the router.

Your explanation wouldn't work for the private IP addresses of 10.0.0.0 or 172.16.0.0. If I'm assuming correctly. Those would get a subnet mask of either 254.0.0.0 or 255.254.0.0 if I'm thinking this through correctly. So one more question.

      @@jimvalim1567 You can use any subnet mask on say 172.16.0.0 as long as it does not exceed the scope of the 172.16.0.0/12 mask. I.e. it's perfectly fine to use 255.255.255.0, 255.255.254.0, 255.255.255.128 ,etc Just size it according to your needs.
      The way demonstrated in this video is demonstrates how one could configure a larger subnet using a typical home router setup. Personally, I'd rather use VLAN's /different subnets and a more standard layout for the subnets. But to each their own. For example, most home subnets typically won't have 30 servers, 400+ clients, 14 printers, etc sitting behind a consumer gaming router on a single subnet. Some might think that obscuring the router IP by choosing an odd assignment for it is security; reality is that every client in the network will have that particular setting in the settings, whether it's dhcp or manually assigned ( gateway address ).
      This is not meant to be a critique of this video; to each their own; there are literally an almost infinite number of ways to configure one's home network or small business network. Worse, as time goes by, it will undoubtedly become necessary to re-architect the network, to either expand it or completely rehash the network as it is.
      Times change; so do the needs of the network; 15 years ago, IOT devices weren't common; nowadays IOT devices are; same thing with smart phones, tablets, and other such devices. 15 years ago, I only needed basic wi-fi, and a single /24 subnet ( could use something smaller, but conserving private IP's makes no sense to me ) . Also, I would never have needed more than say a dozen devices on my network, but that does not mean I would configure my network with a /28 subnet ( 255.255.255.240 ) mask either.

      Understanding subnets is a VERY useful piece of knowledge when you are into computers and networking technologies.

Not to say I was useless, however I was VERY embarrassed a couple of years after setting up an Ethernet network for a rather large software development team in a mid-sized New York Bank. It works, but was quirky.

    I got to maybe 2:40 and I am bailing out. Why? Well, I was curious as to that you were going to say. Why? Because there's a lot of bad advise on FB these days regarding setting up networks. So, was yours going to be better then the rest of the bad stuff? Sadly, no. Why do I say this? As a now retired network from 1981 through 2017) , and a home/small business network user now, I have seen a great deal of poorly designed systems. In less than three minutes, you made three problems with bad assumption and bad advise, would it get worse going forward? How could it not?
    Example #1: in most locales in the world these days, though at times the ISP's tech might call what they are providing you with as a modem, most often is is a router. Is it possible that you will have a modem? Sure, but not as likely.
    Example #2: A modem will provide only one IP address, and that is why the customer needs a router... but if the customer was given a router, would they need one based on your assumption? Or are you hawking a product? Maybe that router?
    Example #3. Is a commercial 'all-in-one router / WiFi your best design? No. For many reasons: (a) the software on the router will likely never get updates and is therefore a security problem; (b) the processor in these devices, and the internal switch fabric can't handle robust LAN traffic and at the same time the huge number of small SIP/VoIP packets; Adding firewall, port forwarding and other rules will likely exceed the memory space inside the type of device you are pushing.
    While home user *might* not have these needs, a home office should consider: (1) can/will the ISP provide a device in bridging mode? Running PPPoE to a CPE is better that having IP on the ISP supplied device (2) a FreeBSD or Linux router/firewall such as pfSense or OPNSense or like device -- without WiFi should sit behind the ISP device and ONLY be connected to a low cost managed switch. The switch can connects to WiFi APs placed where the office and users need them. That is then very basic a proper designed home office without considering CCTV and Iot, with can add far more complexity.

      @@PE4Doers,
      OK, so let’s start with you last comment first.
      “Please make sure you know the security risks of some of the marketing (and insecure) technologies you mentioned in this comment
      Are you kidding me? You are recommending a product that is 100% assured to have major security holes if only because the manufacturer will stop issuing software updates within 24 months (if not far fewer) of the product no longer being sold in favor of a newer product.
      Do all devices connected to the Internet have security risks? Well, duh, that’s why we are constantly needing to apply security update and limit exposure.
      To that end, (and I speak as having started and owned two ISPs [one of which, started in 1994 still exists]) no ISP providing residential connection devices does a good job of upgrading the software on the end equipment. Part of the reason is that the eproms in most of these devices barely hold enough for the instruction set of the device when manufactured. For that reason, turning the device into a bridge is the safest bet as you are leaving level 3 and moving to level 2. That means the ISP can maintain the security issues on its CO or remote hut equipment and you maintain your side.
      Do you know the specs of the processor in your chosen router? It is optimized for WiFi. It has limited switch fabric and can’t properly support a fully loaded set of 1G wired connections to its switch ports. Did you bother to test what happens to even moderately heavy switch traffic does to the quality of VoIP traffic, especially if that VoIP traffic is coming over a wired device?
      That router you were holding up makes a great AP for a small office setup. That means no public IP exposure. It means you can block its private IP from exiting the gateway.
      Using a dedicated router/firewall that can get regular updates from ONPSense or pfSense along with OS security updates is far safer than the type of device you were showing and so I am literally bewildered by your comment about the security risks of my recommendations. What is it that has you all hot and bothered? Are you afraid someone will hack FreeBSD but not a OpenWrt device? Or maybe you are worried about the managed switch? Or is it an AP, which could be the very device you were holding up? WHat the f*ck are you talking about?
      As to not watching the rest. Well now, why bother? Your beginning was so wrong, what migt you say that would make it better, other than to say next... “just kidding, that was all BS, and now for the real advice.” But you didn’t right?
      You may well be all you way. Could be. I have over the many years not hired many who come with like credentials. For reference, I got my first POC handle from the Internic, long before there were RIRs. And so, when ARIN was formed, my handle changed from ML84 to ML84-ARIN. (My POC handle was retired from the database when I transfered my last IPv4 assignment and released my IPv6 allocation.) Have you looked at any current POC handle? How many digits follow the initials? I got my first allocation of IPv4 from what was later called, the swamp. And I have had to manage security for an entire ISP. I sold, programmed routers, switches, PIX units and later their ASA Cisco devices commercial for three decades, {Fun fact, did you know that in 1995, the entire worldwide BGP tale could he held in a fully loaded Cisco 2501 switch? That was in the day when T1’s were considered fast, and an OC3 was really cool.]
      So when I say you are wrong, well, Sir, you are very wrong.
