So you need to enable voice and video communications with Windows Messenger through a non-UPnP firewall...
To enable voice and video communications with Windows Messenger (4.7) through a non-UPnP firewall (such as the brilliant Vigor2200usb), configure the firewall to allow incoming traffic on UDP ports 5004 to 65535.
For other purposes, enable the following ports:
- File Transfer: 6891 (to allow 10 simultaneous file transfers open ports 6891 through 6900);
- Application and Whiteboard Sharing: 1503;
- Remote Assistance: 3389.
I am connected to a campus network and there is no way I have been able to convince them to open the other ports to enable me and my friends use our webcam and other services that requires opening this ports.
Is there a security risk for them if they open these ports?
Is there no way for me to achieve this remotely? What can I do to enable me use my webcam? Help will be very much appreciated.
This is a very old post Johnny; I can't be sure these port settings are still correct (and haven't run Messenger in over a year). If your campus IT staff won't open the ports then I guess they do perceive this to be a risk—or perhaps they are merely trying to preserve network bandwidth by disallowing videoconferencing. I know of no alternative options, but these would in any case be mute without the cooperation of your local IT guys. It's up to you to convince them of the academic benefits of what you are trying to achieve!
