Please help cluster IIS + apache in the lan

[charlie_21]

Dear People,
I have an 2000 server with IIS running on the adsl connection, but in the internal lan i have an redhat appache with an nice site,.
But i can only see it internal with ip adress 192.168.1.221 there it's oke.
But my external nr is 81.204.73.15 and it is the iis now on the 2000 server.

How can i cluster or route or portmap this,
So if someone type's 81.204.73.15:81 it goes to mine 192.168.1.221 apache and shows the content ?? instead of the iis on port 81
there has to be a way , but i don't know how yet..if this works i can do it with all my linux servers in my lan , the all have a service i could use online so please people is it done before and HOW ???

The simplest way is to start up Apache for Win32 on port 81 of your external server.

If You have trouble with this, or You can't do it, try to add more info on external server (at least running OS)

Good luck
