The ports are usually dynamic, so if you are setting absolute port
numbers then it won't work if you're changing venues.
If it's a Windows XP box, then install service pack 2 since then you
can set exceptions for specific programs (and it will prompt you to do so).
For Linux machines if you allow traffic with a destination of
224.0.0.0/8 for higher numbered ports, i.e. 50000-65535 then you should
be okay. If that's not fine grained enough you can always use 'lsof' and
grep for the exact port numbers and write a script that modifies your
firewall (I did one for a bridge)
