I believe I have the correct access-list and static mappings in place, and all mappings on the outside interface IP 75.xxx.xxx.129 work correctly. But as shown in my config below, the secondary mapping for 75.xxx.xxx.131 does now work. What am I missing?

Any help on this would be greatly appreciated... I am sure it is some simple item I am overlooking... Thanks in advance!

 

I'm not an expert, but in our config on our 515, I have the access list as below. Then I have the static mappings with the IPs. That might be your issue. I am running 8.0(3) though.

access-list acl_outside extended permit tcp any any eq www
access-list acl_outside extended permit tcp any any eq https
access-list acl_outside extended permit tcp any any eq smtp
access-list acl_outside extended permit tcp any any eq 465
