Hey scty Library,

how it works so that I can build my self a
router/firewall and mabey a VPN. 

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.   

Rick
