I normally go with 135:139 as they are noisy ports. On a public
network I have a list of ports I drop because they are noisy


-A INPUT -p tcp -m tcp --dport 67:68 -j DROP
-A INPUT -p tcp -m tcp --dport 135:139 -j DROP
-A INPUT -p tcp -m tcp --dport 445 -j DROP
-A INPUT -p udp -m udp --dport 67:68 -j DROP
-A INPUT -p udp -m udp --dport 135:139 -j DROP
-A INPUT -p udp -m udp --sport 177 --dport 177 -j DROP
-A INPUT -p udp -m udp --dport 445 -j DROP
-A INPUT -p udp -m udp --dport 1024:1030 -j DROP

The 1024:1030 UDP drop the enormouse anmount of UDP pop-up spam.
