You may need to supplement this article above with other
HOWTO's/tutorials/articles. I notice for example that it doesn't
mention configuring /etc/network/interfaces at all.
The other thing I don't recommend (and this is just my opinion, based on
my own experience) is trying to cook up homemade firewall scripts. This
topic is complicated enough, and there are a lot of subtle details that
create opportunities for security issues. If "security" is a concern,
and it should be, I say leave firewalls to the professionals: find a
good 'firewall script' that allows you to specify what you want at a
higher level, and then the script will crank out the proper set of
iptables rules. Two examples of firewall scripts are:
- - shorewall (no GUI, just edit some text files according to the
- - firehol (same, no GUI).
The firewall needs to be set up carefully, methodically, and with
attention to detail. Once it is in place it will handle the
ipmasq/NAT/port forwarding (different people use different terms)
