You need a Linksys router.  
It will interface with Comcast, and you can set it up to do the DHCP 
internally.  Besides doing the NATing, and newer Linksys have firewalling 
capabilities built in.

However, I think you can override the DNS.  I'll just have to look up how 
again.  I think you put a line such as the following in the interfaces file:

dns static

or 

dnsdomain myhome.com
dnsserver 4.2.2.2
dnsserver 3.2.2.2 or whatever.

I can't remember, but maybe this will spark someone else's memory.
