I've got a SonicWall TZ210 which connects to the WAN via PPPoE on the X1 interface. I've got a /29 subnet routed into the box, and everything is running fine.
Now, I need to route one of the WAN IP addresses directly to an internal machine without any NAT being performed on the firewall.
I've set up a test network in which I assign an interface as part of the DMZ zone and set the interface to Transparent IP Mode, set the WAN IP up on a test Ubunutu box connected to that interface, and everything is running fine.
However, when I come to replicate this on the live TZ210, which has PPPoE on the WAN interface, it gives me an error
Error: Index of the interface.: Bridged-to interface must have static IP assignment, meaning this configuration won't work because of PPPoE.
What's the best route forwards with this?
