ip over ip tunneling

[Ralph W. Reid]

What you are describing here sounds like network address translation
(NAT) using masquerading.  I have not done this for a while, but the
file /usr/doc/Linux-HOWTOs/Masquerading-Simple-HOWTO proved useful
once I found it on my Slackware system.  As I recall, the systems must
be able to communicate with each other first before NAT will work
(kind of follows if a connection to the outside world is to be
established).  The examples in the file I specified above are pretty
basic, and as you get more involved with firewalling, you may want to
do more with iptables.  If you do not have access to the file I
mentioned above, let me know, and I can put it on my web site.  Keep
plugging away at it--NAT and masquerading were pretty hard for me to
figure out at first, but I did eventually get the mess working.  Let
me know if I can provide any more help.  HTH and have a _great_ day.
