Hi Lonnie, This particular customer has 3 different LAN subnets 2 of which run in the same layer 2 switch. The alix device only has 3 interfaces. The pfsense router had a second virtual address on one of the LAN ports allowing both networks to communicate with it. I was hoping to replicate the setup with AstLinux without having to move one of the subnets into the other.
