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

This entry is part 9 of 12 in the series Getting started with Microsoft ISA Server 2006

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 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.

    Hi

    I’ve only used ISA2000 that came with SBS and didn’t have any problem.

    I’ve just installed sbs2003 and the clients can connect to the internet and internal network fine, but when I’ve added ISA2006 none of the clients can access the server or internet, uninstall isa2006 and they’re fine.

    I assume I’m missing a firewall policy to allow access to the internal network? I’d have thought it would have been already open, but I’m new to this.

    Any advice? SBS2003 with ISA2006 installed 2 nic’s

    Regards

    Mark
