IIS works as a gateway

Hi,

I have the following architecture :

Client Browser -> Web Front End -> Firewall -> Web Application -> Database
Server

I have an issue in the Web Front End. Basically i have installed IIS in the
Web Front End machine.

I would like to know what are the configurations for IIS to route all the
HTTP traffic from client browser to the Web Application through the firewall?
The firewall will drop all the connections NOT originated from Web Front End,
that is why i placed the Web Front End to act as a gateway. I would like to
know the IIS configuration to act as a gateway.

In my experiment, i have configured a default website and then placed a
Response.Redirect command to route the traffic. But i have analyzed that
Response.Redirect will just give the Web App IP to client browser and then
the client browser connect directly to the Web App without going through the
Web Front End.

Thanks for your reply.

Hadi Teo.

I don't want to go into semantics but what you name "Web Front End " is
actually a reverse-proxy.
I would therfore use a real one instead of IIS (ISA, SQUID, even Apache can
do)

If you want to stick to an IIS-based solution, maybe this ASP.Net code can
help: http://www.codeproject.com/KB/web-security/HTTPReverseProxy.aspx
