I have 2 Servers and the network looks like this:
Server_A (Ubuntu) -> Firewall/Router -> Internet
Server_A can connect to any server on the internet.
Server_B (Ubuntu) which is directly connected to the internet.
No restrictions in port forwarding or any Firewalls on Server_B
I can't connect to Server_A from the internet because it is inside a local network and port forwarding is not possible here, I don't have access to the router.
Can Server_A connect to Server_B so I can connect via SSH to Server_B and communicate with Server_A?
