Greetings NetBSD users:

I've have a TCP/IP lan which I've set up with with non-routable Intranet
IP numbers (192.168.0.X).  One of the computers on the lan is an i386 box
running NetBSD 1.2, with PPP and no IP forwarding.  That computer has a
dedicated PPP connection to the Internet with a static IP number, which 
through the use of various proxies (Apache, Sendmail, Named, etc.) is the
Internet gateway and firewall for the Intranet lan.

     Anyways, although this solution works, it is not very scalable, and
is quite restrictive in that proxies have to be installed for every
addition Internet service I wish to use on the lan.  :-(  To solve this
problem, I wish to replace all of those proxies on the gateway with a
single transparent proxy that works with address translation, so that
the lan IP numbers (192.168.0.X) of Internet packets going through the
gateway get translated to the "real" static IP number of the gateway.
The Cisco 700 series routers are capable of this, but I was hoping to
do the same with an i386 NetBSD box.  Better yet, I would also like
some packet filtering abilites with the transparent proxy for added
security.

     Does anyone have any suggestions on what software / configuration
can be used to set up a transparent proxy with address translation that
can be installed on an i386 NetBSD lan gateway?  Any help would be
appreciated.

Sincerely, Alicia.
