Configure Network Address Translation (NAT) on your modem

Network Address Translation (NAT) is an advanced networking setting that most people do not use. We advise you not to disable NAT unless instructed to do so by a qualified technician, as it could open your broadband modem to outside intrusion and create a security risk.
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 http://192.168.0.1 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 "NAT" in the left sidebar. 

6.  Follow the steps to edit the NAT settings:

  • Step 1:  Enable/Disable NAT (we suggest keeping enabled unless advised to do so by a qualified tech)
  • Step 2:  Click "Apply" to save your changes.
NOTE: CenturyLink recommends that you keep NAT enabled. Changes to this feature will reset some of the other settings on the modem. Do not proceed without understanding the technical impacts of using this feature.
