there may be other ways -- but the way i do that is to set up
PORT FORWARDING:
where the main contact/server is
http://xyz.somesite.tld:80/ == 1.2.3.4
and a behind-the scenes localnet addres you're trying to reach
from outside might be 192.168.12.34:
http://xyz.somesite.tld:12345/ -> 192.168.12.34:7777
this will have your server at 1.2.3.4, which doubles as, say,
192.168.1.1 on your internal lan, forward any request that comes
in on port 12345 (via the 1.2.3.4 interface) to machine
192.168.12.34 port 7777 --
For 2.2x kernels, replace 'ipportfw' and 'ipautofw'
with 'ipmasqadm portfw' and 'ipmasqadm autofw'
# ipportfw -A -t ext.ern.al.ip/port -R se.rv.er.ip/port
where -t is tcp, or replace it with -u for udp
# ipautofw -A -r proto low high -h se.rv.er.ip
where proto is tcp or udp, low is the first port, and high is
the last port (ipautofw is good for a contiguous group of ports)
...as gleaned from http://lrp.c0wz.com/dox/portfw.txt
so, for my potato on 2.2 i'd use
apt-get install netbase # probably have this already
ipmasqadm portfw -a -P tcp -L 1.2.3.4 12345 -R 192.168.12.34 7777
to learn more, try
ipmasqadm portfw -h

DEBIAN NEWBIE TIP #12 from Will Trillich <[EMAIL PROTECTED]>
:
Where is the DOCUMENTATION? It's all over the place... and there's
lots of it. Much was written for non-debian distributions, and
much was written long, long ago. But try these anyhow: on your
own system, try "man" and "info" and "apropos", and also look
under /usr/share/doc/<package>* ... Online, there's linuxdoc.org,
debianhelp.org, and debian.org/doc/ of course. Also try
http://newbiedoc.sourceforge.net/general/index-deb-help-sys.html
