Before you move forward with port forwarding, make sure you have the following:

  • The IP address of your router.
  • The IP address of your device.
  • TCP and UDP port numbers. 
  • Remote IP address.

Here are the steps to configure port forwarding on a CenturyLink modem:

  1. Open a web browser and type the IP address of your modem into the address bar. The default IP address for CenturyLink modems is usually 192.168.0.1 or 192.168.1.1. But you can find the correct address in your modem’s documentation or by contacting CenturyLink customer support.
  2. Enter your modem’s login credentials. CenturyLink modems’ default usernames and passwords are usually “admin” and “password,” respectively. If you have changed these credentials, enter the new ones.
  3. Once logged in to your modem’s configuration page, look for the “Advanced Setup” or “Advanced Settings” section. This may be located under a tab or a separate menu item.
  4. Within the “Advanced Setup” section, look for “Port Forwarding” or “Port Mapping.” This option may be located under a sub-menu item.
  5. Once you have found the port forwarding settings, you must create a new rule. This will typically involve entering the following information:
  • Protocol (TCP or UDP)
  • External port (the port number you want to open on the internet)
  • Internal port (the port number on your local network that you want to forward traffic to)
  • Internal IP address (the IP address of the device on your network that you want to forward traffic to)
  • Choose “All IP Addresses” or define a specific IP address. 

6. Save your changes and test the port forwarding rule by attempting to connect to the external port from a device outside your network. If the connection is successful, your port forwarding rule has been configured correctly.

CenturyLink uses a variety of ports and protocols for different services and applications. Here are some of the standard ports used by CenturyLink:

  • Port 80 (HTTP) and Port 443 (HTTPS): These ports are used for web traffic, specifically for accessing websites through a browser.
  • Port 25 (SMTP): This port is used for sending emails.
  • Port 110 (POP3) and Port 143 (IMAP): These ports are used for receiving emails.
  • Port 22 (SSH): This port is used for secure shell access to your server.
  • Port 3389 (RDP): This port is used for remote desktop access.

You can also consult your modem’s documentation or contact CenturyLink customer support for more information on the specific ports and protocols needed for your setup.
