Re: Restrict local UDP ports in browser "advanded settings"


This is more or less the argument for a default port(s) for RTP. I think a default port would be a good idea. Much of the IETF disagrees with me. (I note a default port for SMTP has turned out to be sort of useful). The place to have this argument is probably the transport area list as they view themselves s the port police.  I doubt it will go real well but for what it's worth, I would like a default port. I think that bundle with ICE makes it far easier to have a default port for RTP and greatly increases the number of situations where a default port will work.
