Don't forget the gateway.

What?  IOS had a bug?  :^) 

I gotta agree.  While one might make the case that a pnp firewall/hub 
'solution' is better than nothing for Joe Six-Pack and his shiny new cable 
modem, the only way to go for any serious firewalling is to have a box that 
you understand and control.  (Even PIX -- and I hated PIX.)  You can put 
together a decent firewall system for not much more than a D-Link.

With a dedicated firewall box you can run other services for your internal 
network like dhcp and dns, as long as you write appropriate port-blocking 
rules for the external interface.  Keep in mind, though, that every service 
you run is a potiential risk.  The best firewall has no available services, 
even dhcp.

OTOH, if this is a business hookup and one of those drop-in firewall thingies 
are mandated by the boss, be sure to check out the competition.  3Com and 
others make similar products.  I don't know about anyone else, but when 
someone says 'D-Link', 'security' does not immediately come to mind.  :^)
