If they didn't want end users to put the modem into bridge mode they'd just reset the config on sync up.

It has nothing to do with the cable company "provisioning" the router or PC after the modem.
MAC FILTERING FOR XBOX 360 ON SBG6580 MAC
So it's pretty standard on cable that after you change the device (MAC) getting the public IP address, you powercycle the modem to clear the original MAC address from the modem memory which will allow the new device to connect. Just about every cable provider limits modem configs to allowing 1 public IP address (which is issued based on MAC address). If the MAC Address of your Router and/or PC is not provisioned in their system you will not get an external IP Address. The reason this works and other solutions do not is that TWC has to provision the MAC Address of the SBG6580 router portion on their end. If the problems continue, try to change the MAC Address of your network card they may have blocked/black listed this as well. They will not tell you this, because they don't want to go through all the above steps to make it work right! Since you guys suck at customer service, I have provided the solution here for free.

It's policy to not support it, but it's down right rude to argue with customers over it instead of admitting fault. Thanks a lot for not helping anyone on this issue. I'd like to give a shoutout to the TWC Tier 3 support in Colorado. You should now be online with the Motorola SBG6580 into Bridge mode and you can use your own router to forward ports correctly or directly connect it to your PC and configure your firewall. Save all settings and plug the coaxial cable back into the modem and power cycle it. Advanced -> Options -> Passthrough Mac Addresses -> Add LAN MAC Address of the SBG6580 Found in the Basic > Configuration section. Copy and save the LAN Mac Address from the Basic > Configuration Section Advanced -> Options -> Rg Passthrough -> Enable

When modem is back on plug in a computer with an Ethernet cable into the modem.Ĥ Connect to » 192.168.0.1 and login with "admin" / "motorola" The modem will be auto-reconfigured once you plug in the coax cable.ģ. This resets all settings to factory defaults. Hold down the white reset button on the back panel with a pen for 30s. To fix this and have your modem go online, follow these steps:Ģ. They will refuse to provision a new MAC address over the phone and your modem wont go online. When you enable bridging mode and turn the device into a cable modem, you're then passing along your computers and/or routers MAC Address, which is not provisioned in their system. They provision the MAC address (LAN MAC) of the internal router to have access on their network and any other MAC Address such as that of your PC or router, will simply not work. Basically what they refuse to tell you is that the modem has 2 MAC Addresses, 1 for the actual modem (WAN MAC) and 1 for the internal router (LAN MAC). After talking to 3 different reps at level 3 tier support for TWC (1-86) and being told that "bridge mode is not supported" and told other lies, I gave up and fixed it on my own.
