Test websites behind a firewall or VPN

Know how to test websites behind a firewall or VPN using Local Testing

If the local website that you want to test is running behind a firewall or VPN, then you need to perform some additional steps to ensure your network allows connections to the BrowserStack platform.

Prerequisites

Complete the steps in Set up Local Testing.

Set up BrowserStackLocal connection

To test your website hosted behind a firewall or VPN, follow these steps:

1. Ensure that your website is accessible on your local system.
2. Allow Secure WebSocket (WSS) connections to the BrowserStack platform (*.browserstack.com) at port 443. To do this, contact your IT or network team.
   Verify whether your Local Testing setup is enabled. If not, proceed to the next step.
3. If your website or VPN or firewall only accepts connections from certain IP or subnet addresses, enable the Force Local flag.

Launch a test session

After you configure the proxy, you can launch a Live session and proceed with testing. If you already had a test session open, it reloads with the updated Local Testing settings.
