ip route shows any container on eth1 are getting a default gateway of 10.10.0.2 instead of 10.10.0.1.   Arp confirms that the mac is not that off my gateway, but of a switch. 

 

Route on unRAID (gateway-usg resolves to 10.10.0.1)

Technically speaking, it is not allowed to put two interfaces in the same subnet, this will confuse routing (the router).

 

Common approach is to have different subnets on each port, e.g. 10.10.0.0/24 and 10.10.1.0/24. Give that a try.
