DId anyone ever reply to this?
My son installed frostwire. The best idea - uninstall it. Add a local firewall rule to block it (Eg c:\program files\fristwire\frostwire.exe - assuming a default install).
Frostwire like limewire uses TCP/UDP ports 6346 and 6347. You need to block those. I also noted that my sons had been configured for 13507, but it can be changed to anything, so you could end up chasing the culprit for ever.
This is what my access control rule has...
In port filters, after setting up the access rule.
Name=Anything that makes sense to you. Mine says Frostwire
Dest start IP 0.0.0.0
Dest IP end 255.255.255.255
Protocol ANY (so you capture both TCP and UDP)
Dest port start 6300
Dest port end 6400
The add another entry for 13500 to 13510.
I've seen some posts say that you should block ports 10000-65535, but that will also block lots of legitimate programs too.
Note that this is not infallable. P2P programs are notriously difficult to block. Like I said at the start, uninstall the application. I installed MsAfee on the PCs, added limwire and frostwire to the list of disallowed programs, then password protected the configureation. Then they couldn't run the programs even after reinstalling it.
Good luck
