On the two devices LAN not work but AUX (ether2) work OK (shows connection). Can be used AUX as an LAN?
On newer firmware you should be good. (>2.3 IIRC) Be aware however that future firmware versions may (hopefully) offer more control over the two ports (separate routing, firewalling, etc) and it's possible once disabling/enabling the second port is exposed in the webUI that it will default to disabled.
