ubr924 with Charter Pipeline

I recently recieved a ubr924 cable access router as a gift. It would be really nice to use this in place of my current cable modem/Linux firewall combo. I am having some difficulty getting it to work, though. If anyone can give me some ideas, I would appreciate it.

Thanks,

Alan

Re: ubr924 with Charter Pipeline

Seems like the upstream is not syncing up with the new router. Look over these two URL's as they both have some great configuring and troubleshooting links on them. One other thing is that it could be that the ISP is only looking to respond to the original cable modems MAC address and it does not recognize the new modems MAC. You may need to contact them and let them know the new MAC.

Re: ubr924 with Charter Pipeline

Alan,

I had the same problem with Charter. You should be able to simply proxy the old mac address in the new modem. Charter provisions based on geographical area. They also assign mac address ranges to these areas. So, they probably wouldn't allow you to use your own Cable Modem 'cuz then they couldn't charge you. You should be able to grab the mac address off the cable modem and then proxy it through your new device. That is how I got mine to work. I hope this helps.

Re: ubr924 with Charter Pipeline

Actually, Charter in this area does allow customers to 'bring their own' cable modems. I called them with the new MAC address, but I'm not 100% sure that they've added the new one. Not being a DOCSIS/cable expert by any means, I'm not sure if they can have two MAC address' associated with my account. They may be waiting for me to drop off the old modem... I'll have to call them again. I do appreciate the help, and I will post the final solution when it does start working.

Re: ubr924 with Charter Pipeline

That was it. It had not been provisioned. Thanks for the help! Everything (NAT, port-forwarding, firewall feature,etc.) is working...

Re: ubr924 with Charter Pipeline

7rbowenii,

I can not get my ubr924 to work either.

I suspected something like "...i was prohited to use my own modem 'cuz money". So I tried to associated my old Mac with my new cable modem interface.

However, i can only change the mac address on my ethernet interface and not change on the cable interface.

You said "...you simply proxy the old mac to the new modem". My question is; how do you do this?? Any help would be greatly appreciated.
