ANSWERED: How to set up Port Forwarding on your Xfinity Gateway

This article explains how to set up port forwarding for your home network. You also have the option to enable port triggering on your home network.

We offer two ways to set up port forwarding if you rent an Xfinity Gateway:

How does port forwarding work?

Similar to a wall in your home, your Wireless Gateway keeps out potentially harmful risks from the internet while opening doors or 'ports' for safe internet traffic.

Some applications require a designated port to work properly, and that's where port forwarding comes in handy. Port forwarding is also commonly used for:

  • Video games.
  • Some email application ports, like POP3.
  • Instant messaging.
  • Video conferencing.
  • Peer-to-peer file sharing.
  • Remote computer access.
  • Phone service that leverages voice over IP technology.

What is a port number?
All incoming traffic will include a network port number to identify the type of traffic being sent. To find the port number of the traffic you're looking for, contact the service developer or search online. Common port numbers are Port 80 (web servers) and Port 443 for Secure Socket Layer traffic.

What is an IP address?
Every device connected to your home network is assigned an IP (Internet Protocol) address. Your Wireless Gateway communicates with your network devices by automatically assigning local addresses or IP address, such as

  3. Select View WiFi equipment.
  4. Select Advanced settings.
  5. Select Port forwarding from the menu.

    • Note: If you've previously set up a port forward from your Gateway's Admin Tool (, you should see it listed in the Port Forwarding Settings.
  7. Choose the household device for the port forward you're setting up from the drop-down list of connected devices.
    • Note: If you don't see the device listed, it may not be connected to your home network.
  8. Choose from the list of common applications to use a recommended, preset configuration (e.g., Xbox or PlayStation) or select Manual Setup to enter specific port numbers, ranges and/or protocols.
  9. Select Apply Changes to complete the setup of the port forward.
  10. The device you set up for this port forward can now use these settings.
    • Note: If you're unsure which port settings to choose, reference the device manual or the application you're trying to use.
      • Opening unnecessary ports isn't recommended, as it may pose a security risk.


  1. Open the Xfinity app and sign in with your Xfinity ID and password.
  2. Select the WiFi tab.
  3. Select View WiFi equipment.
  4. Select Advanced settings.
  5. Select Port forwarding. All existing port forwards will be listed here.
  6. Select Edit next to the port forward you wish to edit or delete.
  7. Select Delete this Port Forward at the bottom of the screen if removing, or Apply Changes after making edits.
    • Note: Port forwards without an associated device can’t be edited.
      • If you want to use an existing port forward that doesn’t have an associated device, you’ll need to delete it, and then create a new one by selecting Add Port Forward.

Set up port forwarding with the Admin Tool (Xfinity Gateway)

Customers with xFi Gateways can only set up and adjust Port Forwarding settings using the Xfinity app. However, if you have an Xfinity Gateway, you can continue to set up and adjust Port Forwarding settings through the Gateway's Admin Tool (

Follow these steps:

  1. Go to using a device that is connected to your network.
  2. Log in to the Admin Tool:
    • Username: admin
    • Password: password
    • Note: You will be prompted to change your password the first time you access.
      • Please change the password and if required login to the admin tool with the new password.
  3. Select the Advanced menu in the left pane, then click Port Forwarding.
  4. Select Enable. The button will turn green.
  5. Click +ADD SERVICE in the Port Forwarding box. The Add Service page will appear.
  6. Select the appropriate option (FTP, AIM, HTTP, PPTP), from the Common Service drop-down menu.
    • Selecting one of these options will automatically populate the start and end ports below the Common Service field.
      • For a service not listed, select Other and type Service Name in the field.
    • The start and end ports will populate only if you selected one of the four Common Services.
      • If not, enter the port numbers that are required for the game or service for which you want to add the port forwarding rule.
  7. Select the Service Type. The Service Type is the protocol used for sending data over the Internet.
    • The default is TCP/UDP.
  8. Click CONNECTED DEVICE to select the device on your network and populate these fields for the IPv4 Address or IPv6 Address fields.
    • If the CONNECTED DEVICE button doesn't appear on the page:
      • Open a new browser window, follow Steps one and two from above, and go to Connected Devices > Devices.
      • Click the name of the device for which you want to add the port forwarding rule under Online Devices' Host Name.
      • Highlight and copy the IP address.
      • Return to the previous browser window and paste the IP address.
  9. Click Save.
    • You have created a port forwarding rule on your home network, but before you log out of the Admin Tool, take note of your WAN IP address under Gateway > Connection > XFINITY Network menu in the left pane.
      • You'll need this information to begin using the game or service.
