VPN-Kill-Switch on V3.x


#1

Hello,

my question is regarding the kill switch in combination with usage of OpvenVPN connection. I know, that the connection is killed automatically in V3.x when the connection to VPN server is lost, but what are following options in the advanced settings (see my screenshot) - Bring up on boot is logically, but what is Force Link?

For kill switch, we just disable lan zone forward to wan zone in firewall.

This force link is interface’s property. Specifies whether ip address, route, and optionally gateway are assigned to the interface regardless of the link being active (‘1’) or only after the link has become active (‘0’); when set to ‘1’, carrier sense events do not invoke hotplug handlers.

Thanks for the replay.

“For kill switch, we just disable lan zone forward to wan zone in firewall.” --> Is this automatically configured as a standard setting or do I have to configure it manually? If I have to do it manually, is there some tutorial (I’m beginner).

The kill switch is enforced automatically - as far as I understand it, this means that once you have clicked “connect” in the VPN settings, then the forwarding rule is disabled until you click “disconnect” and holds even after a reboot.

OK - thank you for the information!
