Please help me out..

i try to request a mp3 file to my self ( i open 2 mirc's) with the other mirc script, the result was OK, but when someone request mp3 files from me, my mIRC wouldn't send it to them.. why like this?

right now, im not using any kind of routers or firewall, just my cable modem direct to my pc.

im using port 1024-5000 right now!

do i have to use port 10051-10070 in my mIRC options --> Advanced

Im using ircN 8.00 with psyBNC connection
