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! Only change the settings below if advised to do so by a qualified 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."

6.  Select "Auto Select" for the ISP Protocol. Select "Apply."

7.  Select "LAN Subnets."

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, 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.
