I'm currently developing on a system with distributed computers around the country. All of these are sitting behind a NAT and are self-controlled. As a Backup-plan if puppet fails or for other maintenance I thought about a small vpn-network to access the clients by ssh if I need to.
I've already connected the test-client successfully to the server, but I'm not able to ping or ssh to the client or vice versa (which is currently not needed).
The server is also secured by a iptables-setup. I tried couple iptables-entrys which are known for openvpn, but non of them is working.
How do I have to setup the server to get ssh 10.8.0.* or similar working?
UPDATE: I found a false configuration on the client-side. It was configured as tls-client and not client. This made ping and ssh both ways possible.
