How can I connect to a VNC Server thats behind an unconfigured firewall?
If you’ve installed the recently released “Service Pack 2” (SP2) for Windows XP, you have automatically installed a new firewall on your PC that might be blocking VNC connections. To create an “exception” for VNC, follow these instructions: 1. Click Start, click Run, type Wscui.cpl, and then click OK to open Windows Firewall. 2. Click the Exceptions tab, and de-select the “Don’t Allow Exceptions” radio-button. 3. Click Add Port to display the Add a Port dialog box. 4. Enter port number “5900” or whatever port you’ve got VNC on that PC to listen on (port number = 5900 + “VNC Display Number”). 5. Select the TCP protocol. 6. In the Name field, type “VNC”. 7. Click Change Scope to view or to set the scope for the port exception, and then click OK. 8. Click OK to close the Add a Port dialog box. That should do it!
