I am trying to leverage YazFi so I can isolate the guest network I need to provide. My net is pretty simple, I have a router RT-AC65P (running OpenWRT) and a few other devices connected to it. I had an old RT-AC56U so I installed the latest available Merlin FW with the aim of enabling YazFi. I will connect to ac56 via wire, want to keep it in router mode, and I want to use to to extend my wireless network, also provide network via wired connection and it should also provide the isolated guest network. I tried to disable WAN, NAT, DHCP but I either had issues installing Yazfi or had issues accessing the internet from the guest network. The other issue is in that mode /etc/resolv.conf contains the loopback address so DNS resolution does not work locally on the router. I really hope that somebody can help me what to change/set to make it work. Thanks. Oh rc65p is connected to the LAN port of ac56u.
