I'm running openvpn through this command:
sudo openvpn --config vpn.ovpn
which works. I can ping several websites.
After a while, I cannot ping anything anymore, including ip addresses. I can still ping an internal ip. The openvpn command is still running.
After the Initialization Sequence Completed:
Sun May 12 15:58:59 2019 [XXX] Inactivity timeout (--ping-restart), restarting

'Restart pause' happens at increasing intervals.
According to the man page:
OpenVPN to exit after n seconds of inactivity on the TUN/TAP device. The time length of inactivity is measured since the last incoming or outgoing tunnel packet. The default value is 0 seconds, which disables this feature.
So now I'm confused.
