ISA server as a transparent proxy

[FN-GM]

Sorry it took so long.... but here it is.

 

Thanks for all your help

I'm pretty sure that you want to configure a rule in the

Access Policy -> Protocol Rules

 

If I remember correctly you want to configure the rule to allow the http and https protocols from the internal network specified in the LAT to the external network. This should allow your clients to use the firewall transparently.

 

You may need to also right click on HC-Proxy, select properties for the inside listener and change the listening port to 80 but I am not entirely sure as its been a while.

 

I'm still looking around for my old ISA 2k CD so if I eventually find it I may be able to check for you.

Yes basically i want to configure ISA so i don't have to set the proxy setting on clients. On ISA 2004 it will let me do it automatically but i can't do it in ISA 2000.

 

Thanks.

Wow enthusiasm. Anyway I looked it up, I was right it should work, no need to change the listener. https://thesource.ofallevil.com/technet/archive/isa/2000/deploy/isa2kqsg.mspx?mfr=true

 

Near the end of step 4:

 

Creating an All Open Protocol Rule

 

Protocol Rules allow internal network computers access to specific protocols when connecting to Internet servers. Examples of such protocols include the HTTP protocol that allows you to connect to Web servers and the FTP protocol that allows you to connect to FTP servers. You will create an All IP Traffic Protocol Rule that allows your network computers access to all Internet network protocols included in the Protocol Definitions node in the ISA Management console. Perform the following steps to create the Protocol Rule:

 

WARNING:

 

This configuration allows your network computers to access almost all content available on the Internet. However, there are some Internet applications that require special configuration. If you find Internet applications that do not work, please refer to the ISA Server 2000 Resources section for helpful information on solving the problem.

 

1.

 

 

Open the ISA Management console, expand the Servers and Arrays node and then expand your server name. Expand the Access Policy node and right click on the Protocol Rules node. Point to New and click Rule.

 

2.

 

 

In the Welcome to the New Protocol Rule Wizard page, enter All Open in the Protocol Rule name text box and click Next.

 

3.

 

 

Select the Allow option on the Rule Action page and click Next.

 

4.

 

 

Select the All IP traffic on the Protocols page and click Next.

 

5.

 

 

Accept the default settings, Always, on the Schedule page and click Next.

 

6.

 

 

Select the Any request option on the Client Type page and click Next.

 

7.

 

 

Click Finish on the Completing the New Protocol Rule Wizard page.
