no tcp port for incoming connection

[rebse8]

I have been trying to download some files from
gnutella, napster
grokster and I keep getting error messages saying
'NO TCP PORT FOR
INCOMING CONNECTION NO UDP PORT FOR INCOMING AND
OUTGOING PACKETS" I am
in a lan but am using the server pc with winroute
installed., I think
it has a built in firewall which is closing all
my ports. Could you
please advise me how to open some ports to be
able to download? I am
using the server pc (not any client pc). Do I
still have to do port
mapping? My client pc is only used to share the
printer but all web
browsing and downloading is done in the server
pc. Do you think
winroute firewall is also installed in the server
pc preventing me from
downloading...Please help thanks
