iptables init scripts

[Félim Whiteley]

I usually setup my /etc/network/interfaces file so loopback activates a 
iptables save file with:

auto lo
iface lo inet loopback
        address 127.0.0.1
        netmask 255.0.0.0
        up iptables-restore < /etc/network/iptables

That way whether ethX is up/down the firewall is active. I just save a 
standard dump of whatever rules I want to /etc/network/iptables with

iptables-save > /etc/network/iptables

If I want to edit it it's really simple to edit the text file, flush the 
current tables and then just bring down and back up lo and they are reapplied.
