Thanks ariel. This is where my ignorance comes in. I do not want FreePBX to act like a router, but I want it to direct all WAN traffic to a dedicated (SonicWall) router. I do not know how to do this without specifying a gateway IP on an interface. The PBX server does not need to (and I do not want it to) handle any NAT functions.
To rephrase my question, how can I configure FreePBX (via sys admin pro) to use my router as the gateway without specifying a gateway IP on an interface? How else would FreePBX know how to direct traffic out to the internet? I’m obviously missing a key component here that I have not found in my searching.
Thanks again.
