Known Issues

  1. SIP ALG is enabled by default and Verizon has not provided a method for the end-user to disable SIP ALG. It is not known if Verizon has the capability to disable SIP ALG remotely.
  2. DNS servers need to be configured to a set of efficient DNS servers in order to prevent issues with registration on Polycom phones.


It is known that Frontier also supplies customers with ARRIS NVG 468MQ for FIOS and this device and FW allow to disable SIP ALG and modify DNS settings. If you have Frontier then get in touch with Frontier and request to change your gateway to this device instead of G1100 modem.

If this option is not available, then reference the Recommended Routers list and bridging the modem steps below.

This document describes how to configure a Verizon FiOS G1100 (should also work for the Frontier version of this device) to act in bridge mode. This mode deactivates some cable television features, but it allows another router to obtain an IP address directly from Verizon. Other users have documented these steps in publications such as DSL Reports.

  1. Login to the G1100 from a computer that is directly connected to one of the G1100’s LAN ports.
  2. Select Wireless Settings > Basic Security Settings, and turn off 2.4 Ghz and 5 GHz wireless. Click Apply.
  3. Select Wireless Settings > Advanced Security Settings, and disable 2.4 GHz and 5 GHz SSID broadcasting.
  4. Select Firewall, and set Minimum Security for both IPv4 and IPv6. Click Apply.
  5. Select My Network > Network Connections > Advanced. Disable the listed access points, and click Apply.
  6. Note the listed broadband connection. Select it, along with Settings, and uncheck Internet Connection Firewall. Set Internet Protocol to No IP Address.
    Click Apply. At this point, you will lose your connection to the Internet through the G1100.
  7. Click Release and then Apply.
  8. Select My Network > Network Connections > Network (Home/Office). Change the G1100’s IP address to so as not to conflict with the replacement router. Under the bridge section, check Broadband Connection (Ethernet/Coax) and uncheck both wireless APs.
    Change IP Address Distribution to Disabled.
  9. Click Apply. The G1100 is now in bridge mode, so it will no longer obtain an IP address. Connect your replacement router to one of the G1100’s LAN ports. From this point forward, you can interact with the G1100 by connecting a computer to its WAN port and manually assigning the computer an IP address on the network.

Note: If this device is receiving a WAN connection via ethernet, then you can remove the G1100 and attach the ethernet cable directly to the 3rd party/compatible router. Use the following steps.

Important: This will not work if the G1100 is receiving its WAN connection via coaxial cable, This is for Ethernet WAN connections only.

  1. Unplug the power from the ONT (Optical Network Translator).
  2. Unplug the battery backup.
  3. Wait 5 minutes and then plug both back in.
  4. Connect the ethernet cable from the ONT directly into the WAN/Internet port of the 3rd party/compatible router.

Note: The DNS settings on this device are no longer accessible. Verizon has released a firmware update that has “greyed” out this option.
