Now i lost connection all together! i'm realy stuck here!!

i went to my isp today, told them the problem..i thought they blocked ports or something!!!..anyway, they said they refresh my port, whatever that means!! anyway did'nt beleive them.

so...here's my new situation:-

My LW connection status is always "Starting Connection"

i can't see port "6346,7,8" open, thier closed, i check LW listening ports like "58900" and it's open, so i guess with "6346" closed i can't connect to Gnutella network!

i tried other P2P appliocations..same prob, can't connect to
Gnutella 1&2!
i port forwarded them all...is it windows!
