I know some resellers of the old @home ISP service had terrible hierarchies will regaurd to support phone calls. In my opinion if you aren't talking to somebody that actually had the capability of increasing CPE or in some other way releasing the MAC of your Ethernet card in about 20 minutes or so, call no-joy and trade your router in for an "EL CHEAPO" router like linksys etherfast that allows you to simply type in whatever MAC you would like the router to emulate. Then get the MAC of your card (ipconfig /all or whatever) and tell the router to use that MAC. Then the cable modem essentially thinks it's connected directly to your ethernet card....$0.02.

Ullrich; s.eVershAde Cc: [EMAIL PROTECTED] Subject: Re: Question on broadband IP routers using NAT * Call your ISP and ask them to increase the number of CPE devices temporarily to 2. Depending on their DOCSIS modem management software they may be limiting you to 1 CPE (ethernet device). This is done by the MAC address of the ethernet device connecting. A DOCSIS configuration file is sent to the modem during its boot up process and it contains the # of CPE devices allowed. By them temporarily allowing 2, and you (or them) resetting the modem ... will allow your router to get an IP Address via DHCP. After that they can lower you back to one CPE (and hence 1 ip address from their pool). After that your EL CHEAPO router will be on their network and the Internet and it can handle the NAT for your internal network of devices. Some El Cheap routers allow you to enter any MAC address as the WAN side towards the cable modem (or DSL modem as the case may be) and basically allows you to spoof as your PC's MAC address. That would work also in case your ISP doesn't want to increase the CPE even temporarily. ... as a side note, this is the same proceedure that your ISP would have to do if, lets say, your PC crashed and burned (became inoperable) and you bought a new PC with a new Ethernet card that was different than the one you originally installed when you signed up for your service. They really shouldn't have a problem helping you with this. They probably won't want to support much else though as far as your internal network, because you don't pay them for that. ----- Original Message ----- From: "Johannes B.
