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?
