Testing past firewall / Beyond VPN

It has been a long time since this was asked. Maybe things have changes.

I am trying to test a site. It has a firewall and I have to log in through a VPN to even access the site. How can I make webpagetest.org access the site?

There are only 2 ways:

1 - Set up a private instance with agents inside of the firewall.

2 - Poke holes in the firewall for the WebPageTest agent IP addresses that you want to test from. Most of the regions have a static IP now so it’s feasible but usually something the security team needs to weigh in on: WebPageTest - Tester IP Addresses
