Hi all!. I am a network admin from Argentina who want to block the Windows / Linux Client because is killing our bandwidth. I have a firewall Linux-distro (IPCOP) and i did make a rule to drop all trafic from the next IP's range:
Also, i block the TCP/UDP Port 4070. But when i was trying the configuration, i noted that the app it's still working!.
I dont have problem with the Web Client because i blocked it with SQUID service.
