Newbee: Trouble with this "easy" script

Posted 
test_address="8.8.8.8"                                          
tunnel_interfaceWAN="eth0"                                      
tunnel_interfaceVPN="tun1"                                      
init_ping_tries=2    

ping_tries=init_ping_tries
WANup=0

while  [[ $ping_tries -lt 5] && [ $WANup -eq 0 ]]
do
        if ping -c 1 -W 1 $test_address -I $tunnel_interfaceWAN >/dev/null
  then
                WANup=1
        fi
        ping_tries=$((ping_tries+1))
done

if $WANup -eq 0
  then
        echo "VPN is down because Internet is down [exit 0]"
        exit 0
fi

Im pretty new to bash programming, this script should be simple, but I cant seem to figure out why it is not working correctly.

Is there something wrong with the syntax of my while loop or last if statement?
