With his first article for ISAserver.org, we would like to welcome ISA Server MVP Marc Grote who for the past two years has contributed many excellent articles to our sister site - MSExchange.org. This is the first article of a four part series which will show you how to install and configure ISA Server 2004 Enterprise Edition. In the first part Marc will show you how to install and configure the Configuration Storage Server.
In the first two parts of this series on configuring a network services segment behind an ISA firewall, we began by going over concepts and considerations in creating perimeter networks. In part 2, we discussed the initial configuration of the network services perimeter ISA firewall. In this article we’ll complete the configuration of the network services perimeter ISA firewall by creating Web Publishing Rules, Server Publishing Rules and Access Rules allowing access to resources in the network services segment located behind the network services perimeter ISA firewall.
In the first part of this multipart article series on configuring a network services segment using a perimeter ISA firewall, we discussed concepts and issues in perimeter network design and issues related to the ISA firewall’s stateful packet inspection mechanisms. We also went over the sample network design used in this article series. In this, part 2 of the article series, we’ll move our attention to the network services segment perimeter ISA firewall.
The ISA firewall can act in a number of roles: a front-end edge firewall that sits in front of the entire company, as a back-end firewall located behind another edge firewall that might be an ISA firewall or another type of firewall, or a perimeter network firewall that walls off critical network servers and services from the rest of the network. It’s this latter configuration we’ll focus on in this article.
We continue our coverage of installing the ISA firewall on SBS 2003 SP1 with a discussion of DNS and certificates. After that, we’ll get to the fun part – installing the ISA firewall software.
