Microsoft Small Business Server 2003 Unleashed

RRAS provides many essential services to your SBS network. However, many of its functions are determined by the way your server and network are configured.

The four major functions of RRAS are to provide the following services:

  • Basic firewall

  • Network address translation routing

  • Remote access via dial-up

  • Remote access via VPN

In SBS 2003 Standard Edition all these functions are handled by RRAS. If you have ISA Server 2004 installed (as part of SBS 2003 Premium Edition), the first two functions are taken over by ISA Server.

If you have ISA Server 2004 installed, you can skip the following sections up to the "Remote Access Basics" section because they do not apply to you. See Chapter 23, "Internet Security and Acceleration Server 2004 Basics," for information on configuring ISA Server as your firewall.
