I've set up several small businesses and networked households on ADSL and Cable internet and will say that certainly the best way to do it is with a router that also has NAT and a firewall built in. I've found that the most flexible setup is to use an external DSL or Cable modem and hook that to the router. Most have hubs built in too. I have set up several SOHO NBG800 router/firewalls and they work great for about $90 - $100. ICS is OK, but not the most flexible choice, especially since XP. MS has made the configuration simpler for the novice, but has taken away some of the configuration settings that you could change in W98se and ME, i.e. DHCP options.
