HTTP 403 - isapi_redirector

Hi all,

Environement:
IIS 5 (isapi_redirector.dll) (listen on port 80)
Tomcat 4.1.24 (listen on port 8080)
Win2k Avanced Server
Browser: IE 6 or Netscape 7.1

Here is my problem.

I get a "HTTP Status 403 - Access to the requested resource has been denied"
when I try to access a protected ressource(in web.xml) via IIS on port 80 which
redirect to a Tomcat 4.1.24 on port 8080.

Not suprising because the ressource is secured into the web.xml. I use a BASIC
authentification. But the thing is that I never get the pop-up window asking
for my credentials (username/password). So, I never get the chance to
authentificate myself (username/password).

I'm able to surf any non-restricted ressources on the webapp without any
problem. So, the isapi_redirector is well configured.

I've tried to access a protected ressource on the webapp directly on port 8080
(bypassing IIS) and I received the pop-up window asking for my credentials
(username/password). So everything is fine with Tomcat.

I've set the log level to "debug" the isapi_redirector.dll and this is what I
get when I try to access a restricted ressource:

The environement the server is in use NAT (Network Address Translation -
Definition http://www.webopedia.com/TERM/N/NAT.html). Could that be a problem?

I've got a similaire environement but whitout NAT and everything is fine there.
I get the authentification window when I access a restricted ressource. So my
guest is that isapi_redirector.dll block the response (pop-up window asking for
credentials) because of NAT. Any suggestions would be helpfull.

By the way, I tried a FORM based authentification and I had the same behavior
so it is not related to the authentification methode.

Thanks for your time
