Cable Modem and DSL - help!

[Chris Midkiff]

You're right, you need a second nic to connect to an internal network.
Roadrunner cable modems (at least the ones I have used) act as bridges.
They will only pass valid public tcp/ip information.  

The person who asked the original question did not say whether he has
more than one machine (and I didn't want to scare him).  If there is a
local network, masquerading to a separate nic is the way to go.  You
_can_ simply plug the cable modem into the uplink port on your hub, but
then you have the problems (mentioned below) with broadcasting local
traffic as well as local name resolution problems.  Since roadrunner
uses dynamic addressing, you can't even use a host file for internal
name resolution.  (Also makes it a pain to host a page, which was
probably their intent.)
