# This script used for iodine in iOS
# Required:
#          Unix command
#          Network Commands
#          iodine

# Readme:
# iodine has 2 mode:
#                   1. Direct, like normal VPN but using port 53
#                   2. Pure DNS Tunnel, using DNS to encapsulate traffic (-r)
#
# Which mean need add 2 different route, for Direct & DNS Tunnel
# adding default DNS & Server IP to current gateway allowing to establish a VPN via iodine tunnel
#
