Hi experts - I just purchased a new Watchguard X550e for my network and want to verify my settings are correct before my first test run.
My internal network is 10.8.0.0/13
My internal Exchange is 10.8.2.5
My external IP is 12.229.X.X
For the system manager I added the 1-to-1 NAT of NAT Base: 12.229.X.X and real base of 10.8.2.5.
In my SMTP proxy rule settings I have From: Any-External and for the To: portion I added the host IP of my external interface - should i be adding a static NAT here, or the external interface alias? I'm just unsure of the correct settings.
Also, I set dyanmic NAT to be 10.8.0.0/13 - Any/External. Do I need to do anything else with this or is this the only place I need to set it?
