I am tying to configure the 2.5G port (wan/eth1), on an OpenWRT one to allow me to connect a switch to it. The One is currently bridged to my fiber router via the 1G port (eth0). That is all working fine.
I have also deleted Wan and Wan6, but I am not sure how I should now configure eth1. Do I need to add eth1 to br-lan somehow? or should I add it as a new interface? If so what type should the interface be?
