Forward the same port to two different systems

[amd.64]

I have an Exchange server and now a webserver on the same network, both use 443 for HTTPS.

I have a block of five static IPs from my ISP. Is it possible to have the Exchange server coming in on 443 on one public IP and the webserver coming in on 443 on another public IP?

Of course.

[amd.64]

How is this done?

Wan/NAT forward for each of the IP's to the destination host.

[amd.64]

As my domain available which makes my IP address' easily obtainable, I am posting a picture of two of the port forward rules. I believe I have them configured correctly but they still do not work.

If I remove the public IP address from Destination Address and replace it with Comcast Address, just like the other port forward rules they work just fine.

Ok so I have partially figured this out. I need to create virtual IPs.

Problem now is that port 443 is forwarded to the mail server no matter if the url typed into a web browser. IE if the user types in www.mydomain.us or mydomain.us both are forwarded to the mail server even though it is mail.mydomain.us

Port 80 is directed to the web server.
