Thank you Nicolas!

I've noticed there's some meshing going on in the lan ports already by default, but if I chain a lan port of the router to the wan of another one, bmx6 seems to figure out something is going on on eth1, but BATMAN keeps all routes to other nodes via WiFi, even to the one that it has an ethernet connection to.

Also, of course, lan ports have the lan interface installed, whereas I'd like to completely disable it from chef, making the LAN of that router only accessible via WiFi.

In other words, I'd like the exact same config to happen on eth1 as eth0. The reason is I want to do ethernet mesh with up to 4 other routers without needing an external switch, connecting to the single wan port, instead using the built in hardware switch in eth1 that is already part of the router, but with the same behavior of the single wan port instead as being a Lan. 

Basically on the change network behavior webpage p4u wrote [I think] I've learned that lime-hdw-openwrt-wan is autoinstalled on multiport routers, I've tried replicating it for Linux_name "eth1" and changing the default interface "eth0" I've found inside lime-defaults to "eth1" in /etc/config/lime. But nothing changed at all, even in Network > Interfaces. Also I see that by default there are eth0_13 and eth0_29 but only one of those two in eth1 [can't remember of 13 or 29]. Is the correct way to copy the lime-hdw-openwrt-wan to another one named differently and Linux name set to eth1? Chef says not to alter interface specific configuration inside lime defaults, so where should I do that in chef? Should I add a new file? 

Also, I'm looking for the cleanest possible way to do this, to ensure I don't mess up all of the extremely complex interface configuration of LiMe ;]

Thank you

Nk
