Summary: IP Port Forwarding on Dachstein
Initial Comment:
I'm running the Dachstein LRP on a pentium 133 box
with 3com and Network Anywhere network cards, and am
connected to the internet via DSL. The router works
great, but I am now trying to forward port 80 for www
over to a Mandrake 8.1 box running Apache (don't be
fooled, I'm a Linux newbie). I've determined so far
that the ipmasqadm portfw command has to be used
instead of the old ipportfw. I'm relatively certain
that I've got the usage of that correct, and it seems
to think that it is forwarding the appropriate ports
and IPs (and I've tried every possible iteration of
the command and IPs). I've also done some minor
things like move the weblet to port 8000 so it isn't
in the way. I've been at this on and off for a few
weeks so I can't recall every last thing I've done,
but I've looked through the documentation I could find
and still don't have it working. Basically when you
try to connect to the website from outside it acts
like it is opening the page then suddenly jumps to a
page not found message, which indicates it is not
actually forwarding the port. I'm still not sure
exactly how/where to include the port forwarding in
the modules so that it does that on startup. If
anybody has some advice or some documentation that I
haven't found I would really appreciate it!

your statement that you get a page not found message
suggests to me that the portforwarding is working
and the server doesn't like the URL it is being asked to
respond to.
You can confirm that the portforwarding is working by
starting from your external (dialup?) ip and telnetting
into port 80 and entering something like "GET / HTTP1.0"
followed by pressing enter twice. A "normal" browser
would include a header line after the GET that told the
server what host it thought it was talking to, which could
bother Apache if Apache is not configured right.
See your Apache documentation for further information.
Good luck!

The preferred (less-confusing) way of the actual port
forward with Dachstein would be this line:
INTERN_SERVERS="tcp_${EXTERN_IP}_80_192.168.1.1_80"
You will also need to open the port in the firewall with
the line:
EXTERN_TCP_PORTS="0/0_www 0/0_80"
The module you will need to load is "ip_masq_portfw".
You may need to download this module from Charles'
site in the "dachstein-small/modules" branch (in the
/modules/ip_masq directory if you are using the floppy
version. You simply copy this module to a floppy, then
copy it from the floppy to the /lib/modules directory
of the Dachstein machine (make sure the name is correct
after copying it).
You will need to save the "etc" and "modules" packages
then reboot the firewall to have all changes take effect.
I hope this helps,

I put my Ipmasq portfw rules in the port forwarding section
of the network.conf right under the INTERN_XXX_SERVERS
section.... and remember to open the www tcp port just
above in the EXTERN_TCP_PORTS="0/0_www" variable.....
I hope this is right... Newbie also..
if not, hopefully someone will let us both know...
