Unified Communications & Firewalls
I’ve just acquired & started to use Microsoft Communicator, which has varied reviews, but should do what I want it to as I move to Unified Comms to communicate with far-flung family.
However, there’s a snag. The thing connects, then on video calls, after a variable period of time, usually < 10 seconds, bombs out because the router’s firewall thinks I’m living dangerously… thus, lots of reports on the routers log of this type: UDP Packet - Source:ww.xxx.yy.zzz,25467 Destination:aa.b.c.d,17875 - [DOS] Doing a bit of Googling, I understand that video conferencing typically uses a lot of UDP ports. However I’m very reluctant to open them all – after all, a firewall is there to protect me… What do I do next? Any suggestions? |
Use the registry to specify the port or part range:
Description of the Windows Messenger client basic protocol port usage for instant messaging, file transfer, audio, and video Audio and video Audio uses a pair of User Datagram Protocol (UDP) ports for a Real-time Protocol (RTP) stream to transmit data. Video uses Real-time Transport Protocol (RTCP) to control the session stream. By default, the ports that are used are dynamic. However, the ports can be controlled through Group Policy registry settings. |
Never used the software and never will. Opening inbound ports for the benefit of Microsoft software is generally to be avoided. :ok:
However, how about using program exceptions in Windows Firewall, that way the ports are only open for Communicator to use.... Office communicator and Windows Firewall - 0 to 60 in a fortnight OR .... better still.... Use a VPN between locations :cool: |
Ta!
Thanks t'ye both. i'll print out both pages & ponder. Also report back:)
