HOW TO USE

Place the rules.sh and the users files in the same folder (I recommend a folder named portal in the root folder "/portal/")
You can initiate the script by typing: bash /portal/rules.sh initialize
You can grand an ip access to the internet by typing: bash /portal/rules.sh grand XXX.XXX.XXX.XXX (The ip adrress)
If you want the script to run at system stratup edit the /etc/rc.local and add before "exit 0" this code:
bash /portal/rules.sh initialize
