Hey scty Library,

Oops! I forgot about that.
The LinWiz iptables wizards cannot help you, a
router/firewall/VPN application is too complicated for
them.
If you do not care about reinventing the wheel, then
proceed with your learning experience.
If you just want a router/firewall/VPN, look at
Smoothwall. A mountain of effort and expertise has
been put into that dedicated firewall distribution,
and I suspect there is NO WAY anything you could do on
your own could come close.
But if your purpose is to have a learning experience,
then you are on the right track.
