You don't need the DHCP server address, even if you had it, what would you do with it? > On Friday, someone else I know was getting it (cable modem) installed. > I asked them to get the info from the tech, and they were told "Firewalls > do not require the DHCP, or gateway address.

And it is possible they don't use a MAC address based access list. The DOCSIS specification (what cable modems use) has an option to limit the number of MAC addresses that are allowed to pass traffic. After the cable modem sees an address, it will ignore all others until it's rebooted. > All of that is a crock, IMO. They do use MAC assignments.

No, you cannot force them to do anything, nor do you need the information, again, what would you do with the information if it were given to you? > Is there another alternative to using IPCop and not specify the DHCP > server and still get connectivity? I've read most of the current IPCop > thread, but didn't see much relating to the problem I'm encountering. Why does IPCop want the DHCP server?
