I thought I'd seen information about this in the past, but I've been unable to dig it up in the last hour.
I'm looking at different options for segmenting a small office network to support payment card compliance concerns. Nothing fancy, but I need to be able to isolate one of the ethernet LAN ports on it's own segment. I was under the impression based on something I've read in the past that the LAN ports are all switched to a single internal interface and not separately routable. Since I can't find the reference, I'll assume I might be thinking about another device.
However, within OpenWRT settings all LAN interfaces seem to be aliased under eth1 and are bridged with wireless under the LAN network. Will creating a new network with eth2 (shows disconnected even though all ports are physically occupied) or custom port (eth3/4) move the corresponding physical port out of the LAN network? I was also considering whether the interfaces could be addressed as eth1.0, eth1.1, ..., though I haven't had an opportunity to take the network down long enough to test.
