how to configure Multiple webservers behind cablemodem\firewall

you need to perform port-forwarding  for the port 80 on your cable modem configuration so that internet users can access your website.

You can run multiples websites on single server with single ip using the same port 80 (universal http) using host headers

provide me the make and model of the modem so that i can assist you to perform port-forwarding, you may also need to contact your isp in case he blocks the port 80 or he does not allow hosting websites.

BTW....Exchange Server is not the same box as the webserver.  not sure that makes a difference.

because you have modem behind the webserver you  need do port forwarding so that internet users can access the website

I need the request to come in on a different port since Exchange Server is using Port 80.

First, I need to create a subdomain that points at the same public ip address but comes in on a different port than 80.  Is that possible?

I have a Sonicwall TZ 210 firewall behind Cablevision's Cisco router that is set up in bridge mode.  No problem hosting a webserver on our service.

Sorry for leaving this question untouched.  Granting points to Bitla.

Thanks
