Quick question:

I got 2 slate ax, created a vpn server on one and download the configuration to add it to the other one as a client. took the 2nd one, uplaod the configuration, now is setup as a client.

What would be the next step to complete the process? If I were to use it as is, will it make any connection go through the VPN to make sure nothing leaks?

Does firmware 4 have a killswitch?
