I have actually called comcast and got the tech to give me some assistance on the sneak.................
He says " The way the cable modem works is as follows. The dynamic IP addresses
are assigned through DHCP based on the MAC address of the external cable
modem. A coaxial cable connects the cable connection from the wall to
the external cable modem. A CAT 5 cable connects the cable modem to an
internal 10Base-T ethernet card in the Linux firewall box. The card must
be set for DHCP, and that is it! No need to enter a password to connect
since authenication is based on the MAC address of the cable modem
provided by Comcast. One important querk is that it takes about an hour for
them to enter the cable modem in their system. You would have to unplug
the power supply from the cable modem and plug it back it for it to
"reset" and grab an IP address. Other than that, no problems."
Can anyone confirm or deny this????
I'm going to give it a shot
