How do you allow Chrome to access the network in your firewall?

Published in Firewall Configuration 3 mins read

To allow Chrome to access the network through your firewall, you typically need to configure your firewall settings to permit Chrome's incoming and outgoing connections. Here's a general approach:

Steps to Allow Chrome Network Access:

  1. Access Firewall Settings: The method to access your firewall settings varies depending on your operating system and firewall software.

    • Windows: Search for "Firewall" in the Start menu and select "Windows Defender Firewall" or "Windows Firewall with Advanced Security."
    • macOS: Go to "System Preferences" > "Security & Privacy" > "Firewall."

  2. Locate Application Permissions: Look for a section related to application permissions or allowed apps. This section is often labelled "Allowed apps," "Exceptions," or something similar.

  3. Add Chrome to the Allowed List:

    • Click on an option like "Allow another app...", "+", or "Add application."
    • Browse your computer to find the Chrome executable file. It's typically located in:
      • Windows: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe or C:\Program Files\Google\Chrome\Application\chrome.exe
      • macOS: /Applications/Google Chrome.app

  4. Grant Permissions: Ensure that Chrome is set to "Allow incoming connections" or "Allow" both incoming and outgoing connections. Some firewalls may have checkboxes for "Private" and "Public" networks; select the appropriate network types where you want Chrome to have access.

  5. Save Changes: Save the changes to your firewall settings.

Example Scenario (Windows Defender Firewall):

Step Action
1 Open "Windows Defender Firewall."
2 Click "Allow an app or feature through Windows Defender Firewall."
3 Click "Change settings." (Requires administrator privileges)
4 Click "Allow another app..."
5 Browse to C:\Program Files (x86)\Google\Chrome\Application\chrome.exe and select "chrome.exe."
6 Click "Add."
7 Ensure Chrome is checked in the list for both "Private" and "Public" networks (if applicable).
8 Click "OK."

Important Considerations:

  • Administrator Privileges: You usually need administrator privileges to modify firewall settings.
  • Third-Party Firewalls: If you're using a third-party firewall (e.g., from Norton, McAfee, or ZoneAlarm), consult the documentation for that specific firewall software. The steps will vary.
  • Security Risks: While allowing Chrome network access is necessary for it to function, be mindful of the potential security risks involved. Only allow access for legitimate applications.
