Firewall and Parental Control Setup for Wireless Gateways

Now that you’ve mastered the basics, take advantage of the advanced features offered by the wireless gateway and your XFINITY home network.

Getting Started

First, set up your wireless home network.

Once you've done that, you can improve your security, personalize your settings, protect your children and more. We'll walk you through some of the basic features and how to get them working.

Note: If you're interested in setting up port forwarding or port triggering on your wireless gateway, please see the port forwarding information or the port triggering information.

Set Up a Firewall

A firewall is a barrier that controls what kind of data comes into and out of your network. A firewall can prevent spam sites from installing unwanted programs on your computer, protect your personal information from theft, and much more.

Note: Higher security from a firewall can block functions you might use, such as peer-to-peer applications like Skype or Spotify. The default firewall setting on the wireless gateway is Low, but you can change your settings to suit your particular needs at any time.

To set up a firewall, follow these step-by-step instructions:
  1. Open the wireless gateway's Admin Tool at
  2. On the Admin Tool homepage, click Gateway.
  3. Under Gateway, click Firewall.
  4. From there, you can choose:
    • Maximum Security (High), which will block most applications except web browsing, email, iTunes and VPN.
    • Typical Security (Medium), which allows access to most sites and services, but blocks all peer-to-peer applications.
    • Minimum Security (Low), which enables all secure apps. This is the default setting when you first use your wireless gateway.
    • Custom Security, which will allow you to block individual types of traffic, or disable your firewall entirely.

Note: A firewall can be set up on both your computer and your wireless gateway, but more than one firewall can cause interference.

Set Up Parental Controls

If you have kids, you might want to set Parental Controls to help manage what sites and information they have access to on the Internet. Your wireless gateway allows you to block keywords in web addresses and specific sites; you can also control which computers these restrictions apply to.

You can set and adjust Parental Controls using the wireless gateway's Admin Tool at

Managed Sites
Using the Managed Sites menu, you can block access to certain websites from local computers:
  • Blocked Sites: Enter the URLs of the websites to be blocked and set up a time schedule.
  • Blocked Keywords: Enter keyword(s) that appear on websites you want blocked, and set up a time schedule.
  • Trusted Computers: Specify the computers you do not want affected. If a computer is selected as a Trusted Computer, it bypasses the configured Parental Control settings.

Managed Services
The Managed Services menu allows you to prevent access to applications and services.
  • Trusted Computers: Specify the computers you do not want affected. If a computer is selected as a Trusted Computer, it will bypass the configured Parental Control settings.
  • Blocked Services: Define services and ports to be blocked using Parental Controls.

Managed Devices
The Managed Devices menu displays information about devices that can be managed by rules.
  • Add Allowed Devices: Choose which devices, if any, are exempt from Parental Control rules.
  • Rules: Created reports display attempted violations of Parental Control rules.
