No connection when I stop Openvpn from ui

[malex2005]

Hello,

My RaspAp is going strong. Specially with Openvpn, it is great. Thank you very much :)

My little issue is when I stop openvpn from the web interface, the internet connexion is lost. Wifi is still up.
The tun0 is removed so as the network routes so it seems normal there. A reboot of the pi with openvpn stopped does not solve the problem
When I restart openvpn all is back to normal.

Anything I am missing out?

That's an odd one. It's possible that the route created for the tun0 interface isn't being properly removed. To check for this, drop to the shell and execute journalctl | grep openvpn. For example, this sequence is typical when OpenVPN is stopped:

raspberrypi sudo[22418]: www-data : TTY=unknown ; PWD=/var/www/html ; USER=root ; COMMAND=/bin/systemctl stop openvpn-client@client
raspberrypi openvpn[22322]: event_wait : Interrupted system call (code=4)
raspberrypi openvpn[22322]: /sbin/ip route del 192.145.80.123/32
raspberrypi openvpn[22322]: /sbin/ip route del 0.0.0.0/1
raspberrypi openvpn[22322]: /sbin/ip route del 128.0.0.0/1
raspberrypi openvpn[22322]: Closing TUN/TAP interface
raspberrypi openvpn[22322]: /sbin/ip addr del dev tun0 10.7.2.3/24
raspberrypi openvpn[22322]: SIGTERM[hard,] received, process exiting
raspberrypi systemd[1]: openvpn-client@client.service: Succeeded.

This restores the default routing and normal internet access via the AP. You can also try executing ip r before and after starting OpenVPN and compare the results.

Hi

Thanks for your reply! I ran the journalctl command and all looked fine. It turned out my dhcp configuration was at fault as I setup a DNS reachable only with the vpn (pihole on a cloud). I figured this out as a ping to the internet was ok.
