Hi, is it possible to stop outgoing traffic to smb on the router with the following firewall script? Code: iptables -I FORWARD -p tcp -m multiport --dports 139,445 -j DROP iptables -I FORWARD -p udp -m multiport --dports 139,445 -j DROP Is this ok, or is there a shorter more elegant version? Can it also be done through gui options, or do I have to use the script method? Update: This syntax won't work. See my answer on page 2. This will work.
