#This script is designed to monitor access to the destination LAN, and ensure a tunnel is always up if needed.
#Written by Michael (TurboAAA) Mast. Please improve on this!

#1. Check if the tunnel is needed.
#2. If it is needed check if there is access to the vpn server.
#3. If there is access to the vpn server, clear any running instances and start a fresh instance.
