streaming media through linux firewall

[Lee Higginson]

I just recently put a firewall in place using CentOS 4.  I cheated with 
iptables and used Firestarter to set it up which only took me a couple 
of minutes.  I'm also using Dansguardian as an internet filter.  I use 
Rhapsody for music management on my client machines (winXP) and I cannot 
get the audio/video streams to come through the firewall.   Does anyone 
have any ideas on what the problem could be?  Thanks for your time.
