We have two Exchange servers, one 2003 one 2010. We have a block of 10 IP's.  The configuration is similar to below.

2003 box
Internal IP 192.168.1.254
External IP 44.44.44.10

2010 box
Internal IP 192.168.1.253
External IP 44.44.44.11

I forwarded 80, 443, and 3389 from 44.44.44.11 to 192.168.1.253 just like the 2003 box is forwareded. The problem is when I set up NAT.  I configured 1 to 1 NAT just like the 2003 box, but the external IP is not showing correctly.  I then make a Dynamic NAT exception, just like the 2003 box, but then mail wont go out from the 2010 box.

What is the version of WG software you are running.

If running version 7,x then you would also need to add dynamic NAT exception [not needed in version 8.x or higher]
Step 11 in article below [please check all the steps]:
http://watchguard.custhelp.com/app/answers/detail/a_id/2008/kw/1-1%20NAT%20setup/session/L3NpZC9pZTNQZ1M3aw%3D%3D

To verify if you go to website, http:www.whatismyip.com; you see the external IP of WG and not the 44.44.44.11 IP.

Another thing I can think of is that the 44.44.44.11 IP is also added under external alias; remove this IP from external alias as this IP is used with 1-1 NAT.
Steps to configure external alias:

Please check and update.

Thank you.
