4: Basic Remote Networking

The SCS allows remote users to securely connect to local network resources, or two Local Area Networks
(LANs) to connect to each other. This chapter describes how to initialize, maintain, and disconnect
individual remote user dial-ins and LAN to LAN remote connections.
After completing this chapter, you should be able to configure the SCS to support the following types of
connections:
Incoming remote user dial-in
Incoming character, PPP, and SLIP modes
Basic outgoing LAN to LAN using PPP
The functionality described in this chapter may not meet all of your performance or network security needs.
If your network requires more complex configuration, or if you are not using modems, refer to Chapter 5,
Additional Remote Networking, for additional configuration instructions.

4.1 Remote Connection Types

The SCS is capable of two types of remote networking connections: LAN to LAN and remote node.

4.1.1 Remote Dial-in

A remote user, or remote node, connection allows remote dial-in users to securely access network
resources. Users can access network file servers, send or receive email, use the Internet, or remotely
administer equipment. For example, a laptop user on a business trip may wish to access files from a
network's file server. Using a modem, the laptop could dial the SCS, form a connection, and download the
files as if the laptop were directly connected to that network.
