Below is the interesting part of my config. I have static NAT configured and working inbound for the Exchange Server and the Barracuda, however outbound traffic from those hosts comes out as the interface IP. Thoughts? I've tried a number of things (outside, inside), etc... No luck. Any help would be appreciated.
object network obj_any
subnet 0.0.0.0 0.0.0.0
object network DSN-EXCH01
host 10.250.231.51
object network MAIL-IN
host 10.250.231.50
!
access-list outside_inside extended permit tcp any host 10.250.231.51 eq https
access-list outside_inside extended permit tcp any host 10.250.231.51 eq www
access-list outside_inside extended permit tcp any host 10.250.231.50 eq smtp
!
nat (inside,outside) source dynamic any interface
!
object network obj_any
nat (inside,outside) dynamic interface
object network DSN-EXCH01
nat (inside,outside) static xxx.xxx.xxx.25
object network MAIL-IN
nat (inside,outside) static xxx.xxx.xxx.26
!
access-group outside_inside in interface outside
Solved! Go to Solution.

Hi,
The issue here is with the order of NAT rules in the 8.4 version.
A Manual NAT rule takes precedence over Auto NAT (within object group).
So, nat (inside,outside) source dynamic any interface; is taking precedence when going from inside to outside.
I hope this helps.

That makes sense, thank you. Is there a better way to acomplish this then? I see there are some options to insert rules before and after other parts of NAT but not sure what to use just yet.
Thank you,
Curtis

Actually, I just removed that part of the config since I already had an object NAT configured for 0.0.0.0.
Thank you very much.
