I am gonna share bit of knowledge on IPv6. IPV6 is 128 bit adress and it's written in hexadecimal system. Unlike IPV4 NAT is not necesarry for IPV6 to work because there is unidecilion IPV6 adresses avaliable to be distributed to users and that huge number makes subnetting of IPV6 bit tricky. With IPV4 you can make subnet to have specific number of adresses avaliable for DHCP, with IPV6 you don't calculate specific amount of adresses you'll need instead you calculate range of adresses to asign using nibble boundary method. For IPV6 you have two adresses asigned to interface, one is global and one is link local which is used for communication in your network and it's not routable outside of network. IPV6 will soon replace older IPV4. Here's a trick about DHCP. If you're DHCP doen't work properly, you'll see adress asigned but it will begin with 169.254. something. That's APIPA's response.
Look I'm in over my head and need some help. I have a Netgear R6080 flashed with OpenWRT 22.03.5. Stock settings, except for configuring Wi-Fi. I am trying to add an 8 port unmanaged Tenda switch. I go Modem->Router->Switch-> 3 PC's. At best I have only got one PC to actually have internet at a time. Other times, none. I assumed a dumb switch was plug and play and I couldn't mess up. I'm here to ask if there is anything obvious I need to click in the LuCI interface to make it work.
@@pragmaticsecurity so how devices know to which dhcp server connect ? some relay? forwarder? i see that this is missing in part 3 :( . how to do that?
@@kamileqone So when I set a default gateway for a VLAN, that default gateway is that VLAN's DHCP server on pfsense. If you are not using Pfsense you can go to that VLAN interface, select the DHCP tab, and turn on DHCP for that interface.
@@kamileqone Its just a matter of what you have available to you! If you just want to use OpenWRT as your primary router and access point you can let the interfaces run their own DHCP server. I have a lot going on right now but I am planning to come back to this series and flesh out some of the concepts and add more "paths" for home implementation of OpenWrt.
Why did you stop make videos? U did great job, Bro

Your unmanaged switch is not going to do clans. For that you need a vlan capable managed switch.
Not running DHCP server for each interface in DHCP tab?
No, I am using a DHCP server on pfsense! I like being able to see all of my DHCP leases all in one place on pfsense.

so if i use another openwrt router as DHCP server, how to configure it?
