Hi,

I have Microsoft ISA2000 Enterprise Edition installed in my company.I faced with the new demand in this moment and i do not know how to proced.My server run like a p Web proxy and firewall for all my clients, some of them has Internet access based on some groups from active directory, other part do not have this rights.

From domain policy all users that logon into my domain has in the internet explorer connection settings filled automatically, at proxy settings, my isa server.

Anyway I need to configure my isa server to do next thing:

if an client issue a request on the next ip 192.0.0.0/8 on port 80 ( ex: http://192.168.x.x in Internet explorer) then my ISA must do some kind of PAT and forward automatically the request to another proxy 10.55.x.x: on port 3128.

In a few words, my ISA server must be like a gateway....

This is my problem in this moment and I can't find any solution for it :(

Thank you.

Have you checked if the clients are set up to bypass proxy server for local adresses?

Of course, are bypassed all internal addresses.

The 192.168..x.x it is a different ip class used only for a specific application.

I think you don't understand the situation.Let me try to explain a little more:

An client has in internet explorer settings, at proxy option, isa name:port 8080 + the bypassed internal addresses by default logon script .

It is very difficult to ask the clients to modify manually this settings from isa:8080 to proxy server 10.55.x.x, port 3128 when they need to use the application because they do not have the positive rights to do that, and if they will have some users do not have the right experience level to do that.

More clearly than that i can't explain.

What you need to do is to make a destination set that contains the addresses you want to route. Then you go to Network Configuration and Routing. Choose to apply the rule to specified destination set, and choose the one you created earlier. On the next screen you choose redirect to, and type in the site and port number.

This will apply to all type of client requests not only http://192.168.x.x ( ex ftp://192.168.x.x )?

It will only route requests to the destination you specify. But yes, it will apply to all clients.

If a client asks for 193.168.1.1 it will go the normal route, but 192.168.2.1 will go to 10.55.x.x port 3128. If 192.168.2.1 is in the destination set you specify

Ok ..it work but only in cache mode...in firewall and web proxy mode do not work ( standalone or array ).I talk with the Microsoft tehnical support and ISA 2004 seems to manage this problem.
