Firewall 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 and more. We'll walk you through some of the basic features and how to get them working. You can also protect your children by setting up Parental Controls.

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 and log in with the following username and password:
    • Username: admin
    • Password: password (unless you changed it)
  2. On the Admin Tool homepage, click Gateway.
  3. Under Gateway, click Firewall.
  4. From there, you can choose IPv4 or IPv6.
  5. After choosing either, you will see the following options:
    • 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.
