Hello,
I am new to OpenWRT and my setup is as follows:
From my ISP I must use their router (Orange Livebox Fiber). I have therefore connected a LAN-port form that router to the WAN port of the OpenWRT router.
Internet via IPv4 does work, however getting IPv6 to work gives me problems.
Before I flashes OpenWRT I used the Linksys WRT3200ACM router with stock-firmware and had simply setup IPv6 via "passthrough", which worked. However, the Linksys firmware did not allow me to specify a dedicated IPv6 DNS server (which should be my Pihole).
I have tried to set the DHCP settings (Router Advertisement-Service, DHCPv6-Service, NDP-Proxy) on the LAN-interface to "relay-mode", however without success. I cannot find the setting to correspond with the "passthrough" from before.
Anyone knows how to setup OpenWRT with luci to get IPv6 to work in my setup?
If any more info is needed I will try my best to supply it!
//Edit: The OpenWRT router has IPv6 internet, and I can ping ipv6.google.com when I SSH into the OpenWRT.
