[CLUE-Tech] comcast broadband cable modem

[Rita Gibson]

Hello everyone:

I just stumbled on this list. I have been subscribed to the Clue-talk 
list for some time.

I recently switched out an old Redhat 7.3 box that someone else had set 
up for me with squidGuard installed to share my DSL connection with the 
network here at my house. I didn't have a clue how to keep it up to 
date, etc. So I read a recommendation to use a combination of IPCop and 
DansGuardian (internet content filter), found a good howto on the web. 
Also downloaded some add-on features, tested it and now have it up and 
running and have been switched over for about a month. I have Earthlink 
DSL and they use a PPPoE connection which I was familiar with and it was 
very easy to accomplish during the IPCop installation -- 30 minutes and 
the entire thing was up and running with all the updates downloaded and 
installed.

A friend of mine has Comcast and a broadband modem with an ethernet 
connection. She is currently sharing this broadband connection via a 
wireless access point but would like a firewall and a content filter for 
her connection also. (When you have teenagers you do what you can.) I 
thought it would be simple, but discovered that I am clueless as to how 
the connection works with the cable modem. I know how to configure a 
"dialup" modem with IPCop, and the PPPoE, but just can't see what to do 
to configure this cable modem connection.

Of course, if you ask for support from comcast, and mention Linux, they 
immediately do not support that, so they can't help. Can anyone help me 
to figure this out?

Anyone on this list using IPCop? How about anyone connecting to comcast 
via a cable modem with ethernet and a linux box. I am not at my friend's 
house and I don't know the exact modem type at the moment. This was 
originally installed by comcast with one windows computer, then they 
bought a laptop and added the wireless access point, which was fairly 
straight forward. All they know is that it works when they turn their 
computer on.

Thanks for any tips.
