How to 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.
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 settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security key).
You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.
CAUTION!Do not remove or lose your modem sticker, which includes your default admin username and password. These preset credentials cannot be retrieved, and your modem could become unusable without them.
The modem sticker shows you TWO important sets of login credentials. How do you use each one?
SSID and Key/Wireless Password: Used to access and connect to your WiFi network
SSID is the name that will show up on your devices in the list of wireless networks (may have two for dual-band modem/routers)
Key/Wireless Password is the password you will enter on your devices to connect securely to your network
These default settings can also be customized in the modem settings or through the app
Admin Username and Admin Password: Used to log in to your modem settings portal
Access secure settings such as firmware updates, WiFi security, schedules, and more
When connected to your home network, go to http://192.168.0.1 to access the portal (also called the GUI)
These default settings can also be customized in the modem settings
4. Select the Advanced Setup icon in the main menu.
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.
