implement vpn killswitch using route?
I have a headless ubuntu 14.04LTS server that I want connected to VPN all the time. It seems that is nearly impossible using just pptp/pppd. So, barring that, I want to set the kernel default route to put all traffic except 192.168.1.* through the connection ppp0 and not eth0. That way if ppp0 is not available, the only connections that should work through eth0 are local VLAN IP's. Is that possible?
