disable the internet using route del command
IP=$(/sbin/ip route | awk ‘/default/ { print $3 }’)
sudo /sbin/route del default gw “$IP”
echo “$IP” >~/tmp/gw.txtfile will be saved to /tmp/gw.txt to restore the internet connection
cat /tmp/gw.txt
route add default gw <IP address> <NETWORK INTERFACE>Note:

add route to your default network
route add default gw <YOUR IP ADDR> <INTERFACE>
