It is a good idea to block these UDP and TCP ports:

135, 137, 138, 139 and especially 445 on all highsites.

They have to do with Netbios and file shares (SAMBA). Most worms and some trojans use these ports to find their way to other open shares, even if nothing is open they still manage to flood your network. Idiots

Dont forget to block the ports suggested in both the FORWARD and INPUT chains.

The INPUT chain to protect the router itself and the FORWARD chain to stop the traffic passing through the router.
