dummy2tuntap w/BASH --part II

###!!  For the rest of us normal vulnerable people with only one 

physical network adapter and public IP address on it::

sudo ip link set dummy0 up

sudo ip tuntap add dev TAP0 mode tun

=================================== 

To make the deployment faster I am using the below BASH scripts

 to create and destroy interfaces when needed

======================================= 

 nano dummy-bridge.sh

#!/bin/sh
/usr/sbin/tunctl -t tap0
/sbin/ifconfig tap0 0.0.0.0 promisc up
/sbin/ifconfig dummy0 0.0.0.0 promisc up
/sbin/brctl addbr br0
/sbin/brctl addif br0 tap0
/sbin/brctl addif br0 dummy0
/sbin/ifconfig br0 172.22.22.22/24 up
echo 1 > /proc/sys/net/ipv4/ip_forward
======================================= 

nano dummy-bridge-stop

#!/bin/sh
ifconfig br0 down
ifconfig dummy0 down
ifconfig tap0
brctl delif br0 tap0
brctl delif br0 dummy0
brctl delbr br0
tunctl -d tap0
tunctl -d tap1
tunctl -d tap2
tunctl -d tap3
