Sending IPs of email server behind pfsense
-
Hey folks,
I feel like this should have a simple solution, or no solution, and I feel silly asking it, but I've Googled and thought about it… and well, here we are.
Situation is: We have an email server behind pfsense. When that server sends out email, the originating IP that recipients see is that of our firewall. I would much rather the "sending" IP be the public IP of my mail server... but how do I do this?
Thanks guys.

never mind! I knew it was simple.
1:1 mapping. boom. Done.

Or use a port-forward and AON…

I currently have the same problem could you send example of 1:1 input screen

The 1-1 NAT is pretty hard to screw up. A typical entry would be:
interface=WAN external IP=100.200.100.200/32 internal IP=192.168.1.200/32
The AON if you were using port-forwards would be like this:
interface=WAN source=192.168.1.200/32 * * * NAT address=100.200.100.200 * NO
(AON rule must be placed before the auto created LAN rule)
