Around here, Comcast seems to provision a GRE tunnel from the CPE back 
to some router within their network and run it over whatever IP address 
the CMTS hands out to the modem.  Not very efficient, and it mandates 
that you use their CPE (they won't give you the necessary info to set it 
up yourself).

AFAIK, such service is only available on their "business class" DOCSIS 
product and is upcharged even then.
