c1800isr and static nat

I have two exchange 2010 mail servers behind a c1800isr.  Mail server two has a static nat as below

ip nat inside source static <inside address> <outside address> route-map nonat_static.  We want mail server two to send mail out the outside address specified for it in the static nat statement.  It is not doing this however and is sending mail out the interface outside interface address.  Is the ip nat inside statement supposed to force the server to send out that address

Clear the existing NAT translation table as it might have an existing translation before you configure the above static NAT statement.


clear ip nat translation *

The above command will clear all the existing translation.

This was a nat exemption statement that was needed.  Thanks for the reply though
