NAS
The gateway serves as a network access server (NAS); that is, it provides a
service to the dial-in user, such as PPP or Telnet. The NAS is a client of the
RADIUS server on the home/corporate network. The client is responsible for
passing user information to the designated RADIUS server.
NCP
Network Control Protocol. Software that manages the traffic between
workstations and the host. In a LAN, it resides in the server, and manages
requests from the workstation.
network access server See NAS.
PAP Password Authentication Protocol. A method of establishing security on PPP
links where the caller must provide a password in order to establish the link.
Point-to-Point
Protocol (PPP)
Protocol between the terminal and the router. A communications protocol that
provides dial-up access to the Internet. PPP encapsulates common
network-layer protocol specialized Network Control packets; for example, IP
over PPP (IPCP) and IPX over PPP (IPXCP).
PSTN
Public-switched telephone network.
RADIUS Remote Authentication Dial-in User Service. A system of distributed
(client-server) security that secures remote access to networks and network
services against unauthorized access.
RADIUS client A program that resides on the gateway and sends authentication requests to
the RADIUS server and acts on responses sent back by the server.
RADIUS server An authentication server that is installed on a host computer on the corporate
“home” network. All user remote authentication and network service access
information resides on this server.
Remote Access
Server (RAS)
A device that lets a remote node connect to it via a Packet-Switched
Telephone Network (PSTN) or an Integrated Services Digital Network
(ISDN) line. In a Dial VPN network, the Remote Annex performs the remote
access function.
Remote Annex
One of several Bay Networks network access server models that provides
transparent, dial-in access to remote nodes. In a Dial VPN network, the
Remote Annex provides dial-in connectivity for remote users and initiates the
security and tunnel-building functions.
