I'm trying to set up a point-to-point VPN with certificates. The server needs to wait a while for the client to connect.
I'm seeing that the server resets every 2 minutes with the message "Server poll timeout, restarting". Is it possible to keep the server idle while waiting for a client to connect? I've tried 'ping-timer-rem' and adjusting 'keepalive' with same results.
