Traffic from Specific Trusted LAN to go to Specific External Interface
I feel like I must be missing something. The FireBox allows all sorts of fancy routing... failover and such. But what I want is very simple.
We've had a FireBox setup for years... everything works great. We love it.
I want to add a second External interface (different ISP to the first, original, interface), and an additional Trusted interface. I want all traffic from this new additional Trusted Interface to go out (and return) via the second External interface. I want to block any incoming connection requests coming in from that second External interface.
I want everything else (my other Trusted interfaces) to use the first (original) External interface.
Can somebody please guide me in the right way to make this happen?
