Ditemi se sbaglio, sul sito dice:

Stop Logging Hits from the Sasser/etc Worms:
This will stop your firewall logs from filling up with hits on TCP port 445 from the Sasser worm and its numerous variants.
Note that Smoothwall will still block all incoming traffic on port 445 - it's just not logging the hits anymore.

Edit /etc/rc.d/rc.firewall.up and immediately after the line containing

/sbin/iptables -P OUTPUT ACCEPT

insert the following

# drop hits from Sasser and other worms
/sbin/iptables -A INPUT -p TCP -i $RED_DEV --dport 445 -s 0/0 -j DROP



quindi per bloccare le 2 porte di emule dovrei aggiungere:

/sbin/iptables -A INPUT -p TCP -i $RED_DEV --dport 4662 -s 0/0 -j DROP
/sbin/iptables -A INPUT -p UDP -i $RED_DEV --dport 4672 -s 0/0 -j DROP
