OK, that makes sense then.

IP addresses should be attached to the lanX.X interfaces, not to eth0
-- eth0 will only be carrying specially tagged (DSA/EDSA) packets.
So you should move the IP address to lan1.1.

Can you trying pinging via lan1.1 and then seeing if there are
packets transmitted out over eth0, and dump those packets with tcpdump?

That shouldn't be causing trouble as far as I can see.
