Need the firewall requirements for firefox vpn option, currently corporate firewall is blocking traffic.

Hello,

Firstly, the browser level VPN is mainly an IP protection feature. It is not designed for corporate environments. It is not recommended, as it can create security holes.

This feature is mainly designed for consumers, and is systematically disabled in about:policies. To change this, the IT administrator to change the policies in about:policies to make it work.

This is exactly what we are trying to do. I am an administrator and understand what this does, but we cannot find any documentation on the ports and ip 's that it uses. We have a select set of users that will use this for a specific purpose the masquerade outside of the corporate network and looking to set up this browser vpn to do that feature. We need to poke the holes to allow them browser access outside through with this vpn feature. We used another solution before but that software is now unavailable. I have discovered that it does use port 2499 at times to a fastly ip, but it isn't always and we are chasing this in content filtering currently. It would be nice if there was documentation that would be helpful vs trying to reverse engineer it and wireshark.

about:policies IPProtectionAvailable https://mozilla.github.io/policy-templates/#ipprotectionavailable Preferences Affected: browser.ipProtection.enabled

These options are a way to turn off the vpn and on the radio options. That is not what I am looking we want to use this option in our environment but need to know what holes to poke in the corporate FW. What urls does it use? what ports? what ip's? etc That is the information that I am looking for to solve. I have run som wireshark and traffic flows and can find it uses 2499/tcp to fastly, but we are still blocked so something is still be blocked in the 443 stream.
