Recently I have come out a simple implementation based on
live.2008.07.06.tar.gz so that UDP packets could traverse firewall. The
diff file is attached. Actually only source file RTSPClient.hh and
RTSPClient.cpp are changed. This is a simple UDP hole punch mechanism. It works
fine while accessing m.youtube.com behind firewall using mplayer. However I just
wonder that my experience on C++ is not enough. So any comments or any
suggestions are much appreciated! Thanks.</SPAN></FONT></DIV>

Thanks for your reply. These days I have a google on such kind of
<BR>> >technique. It seems that it was called "UDP hole punch". Could
you <BR>> >please tell me which RFC is in progress on such kind of
mechanism? Are <BR>> >there any draft standard now? I just wonder why
youtube and realplayer <BR>> >can works well under no standards on
that. Thanks.</FONT></DIV>

<DIV><FONT face="Courier New" size=2>> This is still in a bit of
flux. Various Internet Drafts have been <BR>> submitted, but it's
not clear yet what's going to go on the standards
<BR>> track.</FONT></DIV>
