K,
Here is my problem and/or question.
I have multiple servers on my green network and sometimes the mail client need to connect to any of the red connections.

example
Single Red interface with multiple IPS
External connection Red
80.80.80.80/26 Primary
80.80.80.81/26 Secondary
80.80.80.82/26 Secondary
80.80.80.83/26 Secondary

Internal Connection Green
10.1.2.1/8

Internal servers
10.1.2.0/8


So when I send a request out to a secondary connection it get blocked. I have multiple mail server on the 10.1.2.0 network.
mail.domain1.com on 80.80.80.80/8 forwards to 10.1.2.2
mail.domain2.com on 80.80.80.81/8 forwards to 10.1.2.3

So mail on domain2 cannot send to domain1.
I am just using DNATing.
