I have setup and used VNC successfully on multiple systems using Linksys or Netgear routers. Here is my problem:
Client has 2 PC's in their office, sharing internet and networked together using SBC/ATT DSL on a 2Wire Gateway, model # 2700HG-B. I have setup the firewall on the 2Wire using tips from www.portforward.com
If I connect my laptop (using the VNC Viewer) directly to this private network I can connect using the 192.168.1.X IP's of the 2 PC's (Running the VNC Server service)without any issues.
But if I enter the public IP say 66.64.20.X of the 2Wire, which is setup in the firewall settings of the gateway to forward to the specific ports on the specific PC, I can't access any of the PC's. I have checked all firewall settings, port 5900 is excluded from being blocked and so is the VNC Server service.
Per the portforward.com setup procedure, I made sure ports 5500, 5800 and 5900 are open for both UDP and TCP. This doesn't make sense since I can access my PC's remotely which are setup behind a linksys router and the only port I opened up is 5900.
Any ideas would be appreciated.
I need setup to allow access to any VNC server I setup running on all supported windows platforms (win 9x, win NT, win 2K, win2k3 server, win XP, win Vista Beta (not as important as others).
I only seem to have this port forwarding/setup problem when clients use any model of teh 2Wire Gateway. The setup is goofy and confusing.
