Re: Real Player Helper in 2.4

[Max Headroom <maxheadroom2323@yahoo.com>]

Bob,
Thanks. But, TCP doesn't need a NAT helper
because only UDP uses an anonymous port
that the server needs to connect back to
the client on. The argument is that UDP
give better performace which is why
I am trying to get a 2.4 NAT helper for
Real Player. Anyone know of anyone else
working on the problem? ICQ would is another
helper I am looking for. Anyone working on
that?
MH
