How to reach Comcast over existing ethernet network from new Debian box?


Challenge + Situation

Challenge: I can ping everything but I still don't have service yet

Situation:
I'm running Debian Sarge on a Freekbox (if you don't know, don't worry).
I'm adding it to someone's existing Comcast service. In his case that leaves him space for 6 more users.
The network was set up long ago on XP like this:

Comcast
Comcast router
Zonet ethernet router
VoIP box, XP machine, newly added Freekbox
Phone

Or if the smileys don't work,

Comcast
||
Comcast
router
|
Zonet
ethernet
router
| | |
| | Freekbox
| |
| Original subscriber (on XP)
|
VoIP
|
phone

dhclient gets me 192.168.1.2 or 192.168.1.6
Then I can ping anything but not http past the Comcast router (Surfboard)
Then I get online over my existing dialup (EFN)
Then I unplug the phone line
Then I surf the internet at will over Comcast - but only at speeds comparable to dialup.

Obviously I am missing some information about Comcast here. Ideas?

Of course, after posting, I noticed that this post is from several months ago. Hopefully it got solved.

That sounds a lot like dhclient didn't get you any DNS servers. Somewhere on the Zonet router should be a list of Comcast DNS servers and IP addresses. For each one, add a line in your /etc/resolv.conf file that is like this:

nameserver xxx.xxx.xxx.xxx (replacing the xxx with the actual IP address)

It is also possible that the gateway is not set up properly. What is the output of route -n?
