Publish (Reverse Proxy) the Address Book Web Components to the Internet

For Office Communications Server 2007 edge server deployments, you must be able to publish (or "reverse proxy") a number of Web sites required for the following:

To enable remote users to download files from the Address Book Service.
To enable external users to download meeting content for your meetings.
To enable external users to expand distribution groups.

The following table shows the specific Web sites used by the Web components in the reference architecture.

Table: Directories used by Web Components Server

Directory	Server Name	Use
https://web.consolidatedmessenger.com/ABS/ext	OCSPOOLWEB01	Stores Address Book Server files
https:// web.consolidatedmessenger.com /etc/place/null	OCSPOOLWEB01	Stores meeting content
https:// web.consolidatedmessenger.com /GroupExpansion/ext/service.asmx	OCSPOOLWEB01	Stores distribution group expansion information

You can use Microsoft® Internet Security and Acceleration (ISA) Server or other reverse proxy in the perimeter network to publish these Web sites.

Follow the steps in the "Configure a Reverse Proxy" section of the document Microsoft Office Communications Server 2007 Edge Server Deployment Guide in order to create web publishing rules on your firewall for the above Web sites.
