Testing Behind Your Firewall

Applies to CrossBrowserTesting SaaS, last modified on April 19, 2021

We have a local connection option which allows you to test sites behind your firewall, or to access web pages that are saved locally on your machine. In just a few seconds, you can establish a connection which allows you to do live testing or screenshots against any of the internal sites you have access to.

To run a Local Connection, launch the dialog in the app:

Enable local connection

An encrypted tunnel is created between your machine and crossbrowsertesting.com. This connection is initiated on your PC when you start a local connection.

Requirements and limitations

Outbound SSH requests to port 443, SSL on crossbrowsertesting.com must be allowed via your firewall. Your firewall administrator should be able to implement these rules for you.

Local Connections for real iPhone 8

http://local/ is currently blocked for real iPhone 8 devices. There are two workarounds to use local connections:

  • Set a hostname in your hosts file to route traffic to 127.0.0.1, and then access that URL.
    For example, if your hosts file has the line testing 127.0.0.1, then you can access localhost in a test via http://testing/.

  • Launch a test using your local IP address. For example, if you are hosting a server on your computer and your local IP address is 192.168.0.100, then you can access your server in a test via http://192.168.0.100/.
