Hi
Hope anybody can help me to workout it.
The goal is I want to publish a website (this is for testing, all that I want to get this site from internet) which is located on the server behind my ISA 2000 firewall.
I tried my best to get it done, but didnt succeed. I will write here what have I done so far, so that you can find out where did i lost.

1. On the Win2K server (server name: TESTSRV) which will play as webserver is behind the ISA and configured as a securenat client.
2. I have put the website contents on this  server with default port (80)
3. The server name can be resolved from anywhere of my LAN. If I type the http://testsrv on the browser on any system in LAN, I could browse the site.

4. ISA server has a public IP, which can be accessible from anywhere the I-net.
5. Okay, now on the ISA Server I have created a destination set with 'testsrv.mydomain.com' with access to any request.
6. Configured Incoming web request listener to the external IP of the ISA server with port 80
7. Created Web Publishing rule to redirect the incoming web request to the specified destination set which points to my web server (testsrv)

Now I connect to internet from my home pc and entered as follows: http://111.111.111.111/testsrv.mydomain.com but it says the page could not be found. Assume that 111.111...is my public IP. even tried with 'http://111.111.111.111./testsrv' but still no luck
Am I correct with all these settings? what should i do more to get browse my site from outside?

Thanks for any help..

If your ISA server has a public IP address, and is listening on port 80, and forwarding web requests to the webserver, you would only need to go here: "http://111.111.111.111"

assuming 111.111.111.111 is the public ISP of your ISA server.

Thanks for the response.
My ISA server also contains the exchage server. I think the default website is using by exchange. Is there a way to connect to my site in this way? 'http://111.111.111.111/testsrv'
or similar ways? The webserver is NOT located in the ISA server. its a server in the LAN.

Thanks

I understand.  but there can be only one computer that listens on port 80 for IP address w.x.y.z

what comes after the slash (the virtual directory) is handled by IIS on that particular machine.  you do NOT specify the computer name in the URL.  if you think that the computer that is running ISA is intercepting web requests because you have OWA installed, then your forwarding of port 80 is in conflict with it.

You are right Adam,
I have OWA in the same ISA Server. It may be conflicting as you told. So, how can I resolve it? Can I stop the OWA and redirect port 80 to web server (Eventhough, i dont prefer it)? Or can I use the different port address to listen the web requests and forward to webserver? any of the way, what should i type in the web browser to get in?
Please help with step by step if there are any config issues..

Thanks

if you configure your webserver to listen on a different port, like port 8018, then you will have to forward port 8018 on our isa server to that computer.

first i would verify that navigating to http://111.111.111.11/ actually takes you to OWA and not to the webserver.

anyway, unfortuantely, after that, you would only be able to attach to your webserver by typing in this address:
http://111.111.111.111:8018/

make sure to delete the port 80 forwarding if you do decide to use a different port.

Thanks Adam, thats a good help of you..
Forwarding you mean the incoming web request listening?
Should I open this port (eg. 8018) manually in ISA server? or will it open automatically as I configure incoming request listener?

To tell the truth, I'm not real familiar with configuring ISA, but if you give me the Version of it you are running, I can do some research
