Liquid Audio problem

Archived from groups: comp.security.firewalls (More info?)

I have been trying with the help a support from liquid audio to get
sound on my computer from streaming audio sites and they recommend I
disable my firewall. I have Mcafee personal fire wall and a router
for my two computers, to disable the router I imagine I would just go
from adsl modem to one computer but of course if liquid audio then
works that doesn't fix my problem of having a home network and my
query is how do I open a port in router, in Mcaffee I believe I can
open port 80.
