Hallo,
i have a problem with my mail-server in our DMZ. The DMZ has private IP-Adresses like 192.168.1.x
teh firewall masquerade that ip-adresses to our official Adress. that works fine. On the external interface i have added another ip-adress for the mailserver, and a SNAT/DNAT give all mail-requests to the mailserver in the DMZ. So far so good. But when we send e-mail the masquerade-rule works and put the external ip-adress into the received-field. This ip-adress is not our MX-Adress.
Now i try to create a masquerade-rule to change traffic from mailserver with the added ip-adress, but i cannot choose it in the drop-down-menu.
Have anyone an idea how can i solve that?
Thanks for help
