Windows SBS 2003 has ISA installed, and used to route RDP requests to a terminal server. I would like to provide remote access directly to the SBS server instead now. The router IP is 10.0.0.1, the external NIC on the SBS is 10.0.0.253 (internal is 192.168... but not used anymore). In the router, I enable RDP to 10.0.0.253 (port 3389). Yet I cannot RDP to the server from an external connection. Even if I stop the ISA and Windows Firewall services, I still cannot RDP to to the server from an external connection. Internal RDP connections work fine if I plug in to the 192.168.... line. What is preventing me from RDPing to the SBS server?
