Cannot communicate from server to client over OpenVPN S2S connection
I have the following S2S configuratiion
Unfortunately, I can connect (ping, netcat, ssh) only from client to the server, but not back.
If I can ssh normally, it means that firewall is not the problem, right? Since packages are travelling in both directions?
Also I can netcat from server to client by a tunnel address of 192.168.27.2, i.e. run
nc -l 1234
on client, and
nc 192.168.27.2 1234
on server and then I see the communication.
What does it mean? How to diagnose the problem?
I made a mistake, I can't connect backwards by any means. But I can see ping traffic with packet capture on a client when pining it from server.
