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.
