Henning Petersen, CRM team support engineer points to a very popular post collaboration with the ISA team.
Last February Yuri Diogenes from the ISA/IAG team collaborated with Henning Petersen from the CRM Team on CRM 3 through ISA Server 2006. After this post, they received a lot of requests for an article on publishing CRM 4 using the Internet Facing Deployment option (IFD). This post is going to answer those requests. For this post we chose to let ISA handle the SSL Certificates as this is the common scenario for ISA deployments although other methods can be used.
We chose to focus this blog on letting CRM handle the authentication while letting ISA handle the SSL session. The main reason for using IFD despite ISA’s ability to provide forms based authentication was that the Microsoft Dynamics CRM Clients for Outlook would run into authentication problems if prompted with an ISA login. In order to get CRM running with IFD a good starting point is to study the IFD guide called How to configure an Internet-Facing Deployment for Microsoft Dynamics CRM 4.0 it can be downloaded from the Microsoft Download Center. The deployment guide will allow you to better understand the CRM 4 IFD concepts before you create any publishing rules on ISA Server.
Adjusting the CRM Server for External Publishing
To deploy this scenario the following topology was used:

We broke it down the IFD configuration in two parts.
