When I switched to iptables I found that I had about 10% of the number of 
rules as I had when running ipchains. Filtering multiple ports on a single 
line and using the ESTABLISHED,RELATED matching rules made this a far 
easier task than I first anticipated.
The only thing I had to use "extra" rules for was to block the stupid 
Windoze machines from trying to access things on the net that I didn't 
care for... and if I ever get around to it again- to stomp the ad sites 
from hogging browser bandwidth.
