MS mentions supporting the H.323 streaming [Realtime Transport Protocol (RTP) over UDP. Currently I am searching to see if the 2.2.4 kernel has any means of supporting this. I think this should tackle some of the issues. I have yet to also find out how the feed works. When the remote user send the feed, does it actually use the clients ip from the app layer or does it look at the ip packet. Judging from the MS article's feel, this is not a concern, but you never know. The reason why it raises questions for me is because I don't see my router dropping or even getting the packets. But then again I even have trouble opening the ports by solutions perscribed???
