Configure a CBRAS connection on your modem

BRAS (or B-RAS) stands for "broadband remote access server." CBRAS is a specialized CenturyLink server that allows multiple sources of internet traffic (cable, DSL or broadband wireless) to converge in a single network, routing traffic to and from remote access devices. 

Caution! The CBRAS configuration will typically only be used by some Static IP customers. We recommend that you do not change the settings below unless advised to do so by a technician. 

Modem Advanced Step 1-4

1.  Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.

2.  Open a web browser and type into the web address field.

3.  Log in to the modem's online user interface (Modem GUI) using your Administrator Username and Administrator Password. Unless you have changed the default settings, you can find this information on the modem's sticker. Note that these are different from your wireless SSID and security key.

4.  Select "Advanced Setup."

5.  Select "WAN Settings" in the left sidebar menu.

6.  Select "Auto Select" from the drop-down for the ISP Protocol, then "Apply."

7.  Select "LAN Subnets" in the next section of the side menu.

8.  Enter the name for the LAN subnet you want to create.  Note: The LAN subnet name cannot contain spaces.

9.  Select the interface(s) you want to associate with the subnet you are adding. Most users will want to select Ethernet 1, Ethernet 2, Ethernet 3 and Ethernet 4.

10.  Select "Enable" next to both "IPv4 Addressing State" and "Modem IPv4 Admin Access."

11.  Enter the "Network Address," "Subnet Mask" and "Gateway Address" that were provided to you when you leased your IP address.

Zyxel users: If you have a Zyxel modem, it may incorrectly fill in the gateway address. Click in the Gateway Address field, and enter the address provided when you leased your Static IP address. If you need help locating this information, contact us.

12.  Select "Apply" to save your changes.
