 | Hi all.
I have linux 9.0 allowing other PCs on my LAN to access the internet using
masquerading. I have a http server on this Linux box that can be accessed
from the internet. You access it by typing http://###.###.###.### in a
browser like Mozilla or Internet Explorer, where ###.###.###.### is the ip
address of the linux PC. All works well.
I have a Windows PC on my LAN running IIS 5.0 which works well on my LAN but
I wish it to be available on the internet though the Linux box. Any one with
the instructions or point me to the right Documentation. I have googled to
my hearts content with no results.
Thanks in advance.
Regards
Leigh

Or you can set up the Linux box as a router, configure IIS in the MS box,
and run all the web design programs you want, saving the finished product to
the [default] c:\www directory.

Well, there are a LARGE number of possible setups possible. Which one
you have is not clear. Port forwarding is probably what you want though.
/sbin/iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 5000 -j DNAT
--to-dest 192.168.1.20:80
That would make http://ipoflinuxbox:5000/ forward the connection to your
IIS server at 192.168.1.20 port 80
(eth0 in -i eth0 is the name of the interface that's on the internet.)

Thanks for that. I understand how iptables works (obvously not good enough
though). I can type http://192.168.1.20 (your example) and my web site
displays fine from any PC on my 192.168.1.0 network. But when I type
http://ipoflinuxbox:5000 I keep getting.the following. There must be
something else involved. (note: There is no firewall on IIS5 PC)
===begin===
While trying to retrieve the URL: http://ipoflinuxbox:5000/
The following error was encountered:
a.. Connection Failed
The system returned:
(111) Connection refusedThe remote host or network may be down. Please
try the request again.
Your cache administrator is root.
===end===

In the example above http://ipoflinuxbox:5000/ will only work for
external clients, on your lan, you still have to use
http://192.168.1.20
(This among other assumes that the ipoflinuxbox is
on the internet, an no firewalling/nat inbetween :)

| Thanks to all who replied. I understand the principlts somewhat but after
many days reading, it sounds simple, I cannot get this thing going.
Now I am a little wiser (I hope)
I am trying to access an internal webserver by using something like
http://XXX.XXX.XXX.XXX:5000
When my linux box (used as the gateway) receives this, it will redirect the
request to http://myinternalwebserver:80. I have tried using different
iptable rules to accomplish this with no result.
I have squid, httpd and named running. Do any of these have a bearing on my
problem. I understand that squid is like a proxy, httpd is my linux web
server (not to be confused with myinternalwebserver), and named is my DNS.
They all seem to work well. I run linux9.0 with an internet connection using
an external modem, and linux box is also connected to a hub (switch) forming
a LAN with myinternalwebserver also connected to it.
In all the literature I have read so far say that this is a simple task.
Does anybody out there have any other ideas, something I have missed, etc.
Thanks in advance.

Leigh

You do this using the PREROUTING and FORWARD chain in iptables on the Linux
machine. See www.netfilter.org for a list of tutorials. Note that the
IIS5-hosted website(s) cannot be available on port 80 because that one is
already occupied by the webserver on the Linux box. So you'll use
PREROUTING to send the requests for some other port - say port 81 - on the
Linux machine to port 80 on the Win2K machine. You would then access the
IIS sites using "http://###.###.###.###:81" (note the port number at the
end of that URL).
If you truly wanted the IIS sites to show up as virtual hosts under the
Linux system, you'll have to do a lot more work (none of which involves
iptables). In that case it's more like having the server on the Linux
machine explicitly forwarding the requests it gets on behalf of the IIS
machine on port 80 to that machine, then supplying the results to the
outside world. I haven't heard about any canned solutions for this,
although I wouldn't be surprised if someone wrote something for it.

Take a look at the Apache ProxyPass and ProxyPassReverse directives.
That pretty much covers what you're talking about.
Probably be better just to run the site on Apache on the L-box,
though...
