To configure your servers for host-header forwarding, you need:
- One or more servers running Microsoft Windows SharePoint Services.
- A device to act as a reverse proxy server, such as a computer running Microsoft Windows Server 2003 and Microsoft Internet Security and Acceleration (ISA) Server 2004.
- A public Domain Name System (DNS) server.
Important The following configuration steps assume that you are using Windows SharePoint Services, Service Pack 1 or later.
The process of configuring host-header forwarding consists of the following steps:
- Install and configure your server farm to run Windows SharePoint Services.
- Create a new public DNS entry to map your public fully qualified domain name (FQDN) to the IP address you will use on the public interface of your reverse proxy server.
- Configure the network interfaces on the proxy server to respond to the appropriate IP addresses.
- Configure the proxy server/firewall to allow Windows SharePoint Services to make connections to the Internet when necessary.
- Edit your Web.config file to allow Windows SharePoint Services to make connections through the proxy server to the Internet when necessary.
- Configure the proxy server to listen for requests on IP addresses.
- Configure the proxy server to publish Windows SharePoint Services.
