Yep, just install the connector on the server in the DMZ. Yeah, you would
have to be crazy to have anything besides a firewall sitting on a valid IP.

The DMZ holds valid internet IP addresses and the firewall does use NAT
between our internal Exchange server and our SMTP server. For example our
DMZ has our external web servers. By being in the DMZ we can have the
firewall block everything except for HTTP, HTTPS, FTP, and another other
ports we want.... this is more secure than just hangining it on the internet
without any firewall protection.
It's been a long while since I have had to mess with our exchange. The
exchange connector.... can this be installed by itself on a server in the
DMZ without the rest of exchange? Probably a stupid question... just
haven't messed with it in 2 1/2 years.
Thanks

I dont know I have my exchange connector on my dmz and my email servers on
my internal LAN. I never had a problem in 2 years. But what ever makes you
guys all warm and fuzzy inside. How could you have your SMTP server in a DMZ
and not use NAT? Isn't the idea of a DMZ to not have a valid IP address to
the outside world? How do you tell your SMTP server to route to a valid IP?

Exactly because of these security issue... Using this no NAT is
needed and there is no exposure of LAN resources...
Thanks again... you are the greatest !
