I am new to OpenWRT and I think I am missing something obvious.
Have the x86 build installed on a PC that has 3 nics (only using 2 atm) and am trying to replace my router that is connected to my fibre connection (Spark Fibre in New Zealand)
I have setup the PPPOE on interface eth0.10 as per some recommendations from this site and connected it to the ONT and it appears to work. The link shows as up with connection time, and from the diagnostics and console I can ping openwrt.org.
On eth1 I have setup a LAN interface that I have connected to an ethernet switch. I have DHCP enabled here.
ip route shows default routes for each interface that appear to be created automatically.
My PC can acquire an address from the DCHP server, but cannot ping any external address (or name resolve).
What do I need to setup to route between the 2 interfaces. I looked at bridge, but that would seem to be exposing the internal LAN the the internet.
