I sent an e-mail about IP chains last week and only got one personal
response. RIGHTFULLY SO, I did some further research and with the help of
the one person I was able to resolve my issue. Further Research does pay
off.
But now I have another issue that I can not find any answers on even after
further research.
I am trying to execute the following command using IPMASQADM:
ipmasqadm portfw -a -P tcp -L xx.xx.xx.xx 80 -R 192.156.0.102 8080
I am trying to get port 80 on my firewall to redirect to port 8080 on an
internal host. But I am getting an error "a page can not be displayed
error". If I try using the port 80, I am connecting to the server. It's when
I try to use port 8080 that it fails. I thought that you can redirect the
firewall port 80 to internal host port 8080? Is this the case? Or are the
external and internal host ports a 1:1 ratio? If you use external 80 you
must configure internal web server to host 80.

This is the single best book for the real-world firewall admin. The
second edition is great, as well. Almost any question which begins
with "What ports do I need to open up. . ." can be answered by it.
Generally, I reach for it more often than any other book in my library
(well, except for the Pratchett Diskworld Companion, but that's
neither here nor there, although mostly not here).
So, uh. . .M3 T00.
