Accessing from outside a LAN

[cadbilbao]

I've got a LAN with a proxy server, with a fixed IP address on the
Internet: 203.X.X.X.

Inside the LAN, I've got a Linux-Apache server. This server has
got an IP address inside the LAN: 192.168.1.17

Of course, you can access the web server from inside the LAN,
simply typing

http://192.168.1.17

Now, I want to access this web server from OUTSIDE the LAN. My
proxy server is MicroSoft Proxy Server, with IIS (MicroSoft's
'Apache'). If I type

http://203.X.X.X

from outside my LAN,
I succeed in accessing proxy's web server, but not Linux-Apache
server.

I would like to change Proxy Server into Linux server. What
must I do in order to access internal web server?

Thanx.

You need a port redirector running on the MS box, or a static route to your webserver and a public ip address.
As far as changing your proxy server you can
look at the details for SQUID.
In this case you would use squid and RINETD most probably.
