Why it is important? If the customer is having cable boxes with Xfinity, and to be more specific, xi5 or xi6 (e.g. MOCA (Multimedia over Coax Alliance) is not going to work if the bridge mode is on. Important: There is an important downside to the bridge mode with Xfinity (Comcast) gateways. Comcast gateways may allow us to enable bridge mode from the web interface: the default IP address will be 10.0.0.1 > default credentials admin/password > from the web UI: Gateway > At a Glance: It is possible to bridge the modem manually without contacting the ISP.It is at the discretion of the ISP, whether or not they will allow the modem to be bridged. Call the ISP and ask them to bridge the modem from their end.

There can be two ways to bridge the gateway:

Technicolor gateway must be bridged to your new router.

They will need to move settings from the old to the new router to ensure your computers and other devices on the network work properly.

Intermedia cannot set up the new router for you, but your IT or the manufacturer of your new router can help you.

Call the router manufacturer or your IT to setup the new router.

This causes phones to stop registering intermittently, causing call and feature failures, usually associated with the URL Calling Disabled error message. They often take too long to respond to the Polycom phone DNS lookup requests.

The DHCP DNS servers cannot be changed from the Comcast default DNS servers.

This causes intermittent one-way audio at the start of calls, phones calls to fail to voicemail, transfer failures, and other strange phone issues.

SIP ALG is enabled by default on this device and there is no option to disable it.
