Need blocking signature for WinMx p2p

[Kasper Winding]

Hi all
Iam working on a school and we got a problem with pupils using p2p programs.

I need blocking signature for WinMx p2p, got most of the others blocked.

Can anyone help me please

Not sure how helpful this is going to be, but you seem to have things the wrong way round. You should be blocking everything except what you want to allow, not having everything open except what you want to deny.

It looks as if WinMX uses TCP6699. Try blocking it in both directions.
