Scenario: I have a single internal host (tape library) that needs to be accessed from two physically separate outside networks. I have 3 NIC's on the box, LAN, WAN, OPT1. I've configured PAT on WAN to internal host connected to LAN on port 23 to test with Telnet - this works fine. I then configure the same PAT (& firewall) rules on OPT1 to the internal host on port 23.

Connectivity from the WAN to internal host work perfectly. But, connectivity from OPT1 to the internal host does not.

Questions:
1. Can I have 2 outside interfaces on pfSense?
2. Is my logic in the scenario above correct?
3. Can I configure PAT on two interfaces pointing to the same internal host and port (23)?
4. Is there another way of getting this to work?

Any assistance would be greatly appreciated.
