DNS resolution for all vpn endpoints can take time. I've seen this
take more than a minute.

Meanwhile, connections would be opened through the original gw
effectively leaking details about the regular connection.

This change makes sure to only let through what is necessary to
setup the killswitch, namely dns resolvers.
