Configuring a a tunnel VA trough a proxy

Hello everyone, I’m setting up VAs to let them to communicate with Sailpoint ISC, the point is that in my environment I’ ve a proxy to let all the communications work. The point is that I want to configure a tunnel to let VA and Sailpoint communicate, but I have the proxy in the middle. My idea is to configure the proxy in a trasparent way, in the sense that it is just a middleware in which the tunnel goes trough. I tried to configure only the tunnel on the VA but it doesn’t work. Anyone that is experienced with this kind of configuration can give my some advices or show me a solution?

For tunnel to work you need to follow the below steps
1- Work with you network team to whitelist the ip ranges for the region which you have opted
2-Copy the key file in /home/sailpoint folder
3-enable the tunnel service

Also you can use sailpoint stunt.sh script to verify if all network setting are ok this script will help you.
refer to the below documentation for more info

I followed this guide but it doesn’t work. It seems like that the problem is related to the proxy that we have in our environment. So i asked if someone else had this problem and how resolved it.
