If you lack Internet connectivity either while using the OVPN desktop client, or afterwards, it is possible that the killswitch have locked itself. There are three ways to reset the killswitch: Restart the client, restart the computer, or through the terminal window/command prompt. If you want to reset it through the terminal or command prompt, follow these steps:
Ubuntu:
- Open Terminal
- Type: the following:
iptables-save | grep -v 'ovpn.se' | iptables-restore
ip6tables-save | grep -v 'ovpn.se' | ip6tables-restore
iptables-save | grep -v 'ovpn.com' | iptables-restore
ip6tables-save | grep -v 'ovpn.com' | ip6tables-restore
The killswitch is now reset and you should have Internet connectivity.
