blocking all SYN's will break too much other stuff (Instant Messangers,
games ...). I think we would be much better off if they (consumer ISPs)
would block 135-139 and 445, maybe 21 and 80.
The rest could be handled with a simple IDS (doesn't even need
to match patterns... just count packets going to 27374 and the like)
I keep saying ISPs would be much better off if they implement these
filters. But not all of them agree. IMHO: less 'zombies' -> better
service -> less support phonecalls.
