Port Blocking

Wed Oct 05, 2005 10:30 pm

I have issued this command to my router in hoped to block the default Gnutella ports to prevent filesharing on this network.


add chain=forward in-interface=client out-interface=client src-address=0.0.0.0 dst-address=0.0.0.0 protocol=udp src-port=6346-6350 \
dst-port=6346-6350 packet-mark="" action=drop comment=""


Is the correct command to block incoming and outgoing traffic through the router on ports 6346-6350?

Thanks in advance!

No, I think the right way would be something like this one. Correct me if I'm wrong.
/ ip firewall filter 
add chain=forward p2p=gnutella action=drop comment="" disabled=no

hey Borage ur idea is correct

and if you know the ports of gnutela ... you can block it manually but try not to specify the interfaces ....

just add protcool: tcp dst-port: xxxx action drop in the forwward chain
