Getting started with Microsoft ISA Server 2006, Part 9: Client Configuration

This article is one of the series of Getting started with Microsoft ISA Server 2006. You can see the index of this series at Getting started with Microsoft ISA Server 2006, Part 1: Introduction.

Client Configuration

From Part 8: Create Sample Access Rule, you have created an access rule on ISA Server 2006. Now, it is time to configure the client computer. There are three types of client that you can choose: SecureNAT, Firewall client and Web Proxy. Each type has a different features, see the table below for the comparison.

On this example, I configure the client computer as firewall client type. But you will see how to configure all types of client.

Client Types

The table below compares the ISA Server clients.

Feature Client types	SecureNAT client	Firewall client	Web Proxy client
Installation required	No, but some network configuration changes may be required	Yes	No, Web browser configuration required
Operating system support	Any operating system that supports Transmission Control Protocol/Internet Protocol (TCP/IP)	Only Windows platforms	All platforms, but by way of Web application

SecureNAT client

To configure client as SecureNAT client type, set the default gateway of the network interface card on client to the ISA Server.
If you are using DHCP, you can configure by add Router scope option to the ISA Server.

Firewall client

Download Firewall Client for ISA Server from Microsoft.
Install Microsoft Firewall Client on the client computer.
On ISA Server Computer Selection, select Connect to this ISA Server computer and type the ISA Server host name.
After the installation completes, you will see the firewall client’s icon on the task bar.
You can view and modify configuration by double-click on the icon and select Settings tab. Also, you can click on Apply Default Settings Now for other users on this computer can use this configuration.

Web Proxy client

Open your web browser. On this example, I use Internet Explorer.
On Menu bar, Click on Tools -> Internet Options.
On Internet Options, Select Connections tab and click on LAN settings.
On Local Area Network (LAN) Settings, check the box Use a proxy server for your LAN and type the ISA Server address and port.

What’s Next

Now I have done the basic configuration on both ISA Server 2006 and the client computer. Next, it is time to test accessing the Internet from the client through the ISA Server. See Part 10: Logging.
