[ale] Modem/router config for Comcast

[ale_nospam at fayettedigital.com (Jim Lynch)]

I have purchased a modem and router to replace the Comcast supplied 
equipment and am wondering how to configure same.  I read in a recent 
thread about asking the company to configure the modem as a pass-through 
device.  That's what I'm currently doing with the existing DSL service, 
letting the router do the PPPoE authentication.  Since I haven't gotten 
any user/pw info I'm making a wild guess that cable modems don't use 
PPPoE??   This is a residential installation.

1. So the questions are, can I get the drones supporting a residential 
installation to configure my modem as a pass-through?
If I do, what's the connection type?
Is there an authentication mechanism I'll need a user/pass for?

2. Or am I going to have to leave the modem alone and  get an IP from 
the modem via DHCP?

I'd rather not have two DHCP servers between me and the network, if 
that's possible.

I know how DSL works but I haven't had any experience with cable to 
date.  I googled for info but all I could come up with was how to 
accomplish #2.

Thanks,
Jim.
