The steps that follow provide a suggested order for configuring your network. For
detailed information about each of these steps, see Chapters 4 through 10.
1.
At the ISP network, configure the following:
• Remote Access Concentrator, serving as the network access server (NAS)
• Tunnel Management Server (TMS), either on the UNIX erpcd server for
the erpcd-based solution or on the service provider network RADIUS
server for the all-RADIUS solution
• Access Control Protocol (ACP) server (only for the erpcd-based solution)
• Bay Networks router that serves as the gateway to the remote user’s home
network
