I have two servers, SERVER-A and SERVER-B. SERVER-A sits behind a firewall on a private IP address. SERVER-B will be hosted in the cloud on a public IP address accessible over the internet. SERVER-A (private IP) can reach SERVER-B listening port, no problem. However, SERVER-B can't reach SERVER-A since it sits behind a firewall.
Is it possible for SERVER-A (private IP) to establish the connection to SERVER-B to create the VPN tunnel? Or would I have to open/forward ports on the firewall so SERVER-B could reach the listening port of SERVER-A?
Here is a basic diagram
