I have a SBS 2003 server with 2 NIC's, one connected to a wireless router and the other to my internal switch. Router is Netgear WNDR3700v3 and I have ports 25,443-444,1723,3389 and 4125 forwarded to the IP of my SBS NIC for my "external" NIC. Last Thursday I lost RWW, email to devices and Internet Connection Sharing. I suspected an ASP.net conflict like I have had in the past, and went in and changed ASP.net from 2.0.50727 to 1.1.4382, however this did not help. I still suspect a firmware upgrade (perhaps the router) or an ASP conflict, however I am yet to find it. I can get internet access to a client PC by adding a proxy directing to port 8080 of my server. Exchange email is also functioning properly. Exchange email is able to send without issue through. I ran SBS best practices and corrected issues, but did not solve the problem. Any advice would be greatly appreciated.
