I have setup a small ms 2003 domain with one dc and a linksys WRT54GS router. The router is receiving a dynamic address from the ISP, bellsouth. The network is 192.168.2.x with smask 255.255.255.0. The server has a static ip and is setup as a dhcp server for the internal network. DHCP on the router has been disabled. The internal network is working fine and everyone can access the internet, no problem. I have opened rdp port 3389 on the router and forwarded to the 2k3 dc. I enabled the server to receive remote connections. I used the public ip to attempt to connect to the dc across the internet but it always fails. I tried the same procedure with vnc remote access but it also failed.
Understand that I am not doing this for the first time. I have successfully performed this many times in the past.
One odd thing I noticed is that from the internal network I can log into the router from a browser using 192.168.1.1 or 192.168.2.1. The router is configured with the 192.168.2.1 address. Any ideas experts?
