1. Remote Access Tutorial By Jeff Blees A general look at what Remote Access means, Multi-Tech’s RAS History and a more specific look at the MA100 ACS.

2. Introduction Acronyms RAS, NAS  Remote Access Server, Network Access Server  A.K.A. Access Server Objectives  To give a remote node (computer), IP access to the LAN the Access Server is installed on, via a dial up connection.  To provide network modem pool functionality (a group of modems on the LAN for workstations to use as needed). “Hey Day” of dial up access servers, early 1990s thru 2001 or so.  Consistent limited corporate need The LAN port uses Ethernet to transceive IP packets. The Serial WAN ports uses PPP to transceive IP packets with the remote node via the dial up connection.

3. Environments Novel Servers, DOS Workstations (early days)‏  IPX via PPP Microsoft Windows  Netbiose over IPX via PPP  Netbui via PPP  TCP/IP via PPP Others  Unix/Linux, IP via PPP  Apple Talk via PPP
