It's Linux man  ;D
No need it is a routing firewall
and if you look at their link or download
page there is one modded floppyfw
called floppyfw-jt which have good DHCP
for your network so all you have to set
in your TCP/IP settings on your two machines
is to obtain IP address automaticly nothing
in your browser, you might need to go to your login page
unless you have an permanent IP then you put user
and pass in config and use he current ppp image if you
use the -jt version you need to change in config
to use ppp.
Just go to their page it is easier than it looks at first.
