Raw message 

Thank you Tim,

You clarified that very well.

I have decided to go with iptables just to lock down my wan interface.  But
I have a question you may be able to answer:

1. What the $TUNTAP variable refers to? Is it tun0? And what the purpose of
tun1? Can I disable tun1 and forget about it or it is neccessary for Grase
to work?

2. Can I just use eth1 and tun0 in my rules or I have to stick with your
variables declared in /etc/chilli/up.sh?

3. Or can I use my own variables in the /etc/chilli/ipup.sh script?

Please clarify the answers and direct me the right when you have time
please. I still learn how Grase is working.

Look forward to your next mail.

Please enjoy your weekend with your family.

Thanks very much

Tubeta
