Remote access server disconnects after a few minutes of inactivity

alanbaker

I'm using OpenVPN with SSL/TLS + User Auth.
If the user goes AFK after about 9 minutes the VPN disconnects. It reconnects right away on return but the Remote desktop connection has terminated by then.

I feel like this has something to do with the ping settings which are
inactive = 0
Keepalive
Interval 10
Timeout 60

The clients are Windows 10 with all other defaults except pushing a route.
How can I diagnose this problem?

If the user goes AFK

Isn't this a Windows 10 green mentality thing ?
Like : shut down (low power) resources because no user present ?

And yeah, if you have a mstsc sesssion open and the underlying connection goes away, that session will close.

I don't think it is a W10 issue. I want to monitor the ping that the server and client exchange. I'm thinking NAT/State table. Any suggestion as to how? Verb level or wireshark?

I have the interval set to 60 minutes as a test and sure enough I'm getting these logs every hour.
But is this an indication that there is a fault? If the pings were going through would it even need to authenticate?
