How can I create a "kill switch" when the ER605 is not connected to the OpenVPN server?
I successfully created an OpenVPN tunnel through my paid PIA VPN service. But when I disable the VPN Client manually, traffic routes back through my main network.
My configuration is very vanilla. I reset the router to factory, programmed the VPN Client, and that's it. It works great when I enable the VPN, traffic gets routed correctly, but when I disable the VPN Client, it's like a normal router passing traffic through my main ISP.
How can I stop traffic from leaving when there's a connection problem to the VPN service? I know it's gotta be easy, but I'm not too familiar with Policies and Rule sets.
Could there be some way to create a VLAN for the VPN, and somehow only allow traffic through the VLAN (VPN), and not the main network?
