I have at&t u-verse with a block of 8 static IP addresses. I am using 2, 1 to a web server and 1 to an Exchange Server 2003. The at&t gateway (private address 192.168.1.254) that serves all IP addresses (public and private) to devices uses port 443 to communicate with the Cisco WAP for wireless u-verse TV set top boxes. I have a Netgear WNDR4500 connected to a port on the gateway that serves the public ip to the netgear WAN connection. The LAN connection is 10.0.0.1 and is on the same network as my Exchange server. When I forward port 443 to my exchange server, my wireless TV boxes lose their connections. AT&T cannot change the port 443 that it communicates with the Cisco WAP. I need to change the OWA port so I can use Outlook Web Access. Can this be done?
