Two Servers: Both have Windows 2003 Enterprise OS
This is a residential operation so the network router is gateway with IP of 192.168.0.1
Our ISP assigns a static IP of xxx.xxx.x.x
One is IIS 6.0 Web Server
One is Exchange 2003 Email Server
Both are running IIS 6.0 (Should they be?)
I am using Port Forwarding on the router, so
Application Port IP
HTTP 80 192.168.0.200 (IIS 6.0 Web Server)
POP 110 192.168.0.300 (Exchange Server)
SMTP 28 192.168.0.300 (Exchange Server)
The MX record for the DNS should point to the static address right? say, xxx.xxx.x.x
assigned by the ISP, in this case both servers are routed through the assigned ISP static address via 192.168.0.1 Router
Is IIS required on the Exchange server? Can I remove SMTP services on the IIS6 Web Server?
What would be the best configuration?
