WatchGuard XTM 330. How to force a PC to use a given external interface
Posted on 2012-09-06
I have several static IP's from my ISP all on the same router. Up to now I use to have two firewalls connected to the router, each one with a different public IP address.
I have set up two external interfaces in XTM 330 (not multi-wan, just two interfaces with the same gateway).
I checked that if I physically unplug the interface 1 (with public IP x.x.x.1), all PCs and servers keep connected to the internet through the interface 2 (ip x.x.x.2) and vice-versa.
In fact, my intention setting up two interfaces was to force the mail server to use interface 2, so its public ip is always (x.x.x.2). How can I do this?
