Dial-up connection

You can use a dial-up modem with the thin client to access a dial-up server. This method provides two ways to access the enterprise intranet:

●An enterprise dial-up server connects directly to the enterprise intranet.

●An Internet Service Provider (ISP) dial-up server provides access to the Internet, from which the thin client must access an enterprise Point-to-Point Tunneling Protocol (PPTP) Virtual Private Network (VPN) server that connects to the enterprise intranet.

NOTE: The dial-up server must be a Microsoft Remote Access Server or another server that supports industry-standard protocols.

Direct connection

This type of connection allows you to connect directly to another computer through the serial port on the terminal.

NOTE: This option is available only to thin clients with serial ports.

Virtual Private Network (PPTP) connection

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables the secure transfer of data between a remote client (in this case the thin client) and an enterprise server environment by creating a VPN across TCP/IP-based data networks such as the Internet. It provides a password-protected path through the enterprise firewall to the enterprise server environment in which the network and session services required by the thin client reside.

Access to the internet requires an Internet Service Provider (ISP). You may use any of the standard means of connecting to the ISP, such as a dial-up modem, cable modem, or DSL modem.

You must first establish the connection to the ISP, before contacting the enterprise PPTP VPN server. This includes dial-up access as well as direct access through the cable modem and DSL modem paths.

Virtual Private Network (L2TP) connection

Layer Two Tunneling Protocol (L2TP) merges Microsoft’s PPTP protocol with Cisco’s Layer Two Forwarding (L2F) protocol. L2TP is basically the same as PPTP; the primary difference is that L2TP supports encryption.

PPP Over Ethernet (PPPoE) connection

This is a connection from the thin client Ethernet port directly to the enterprise intranet. No additional hardware is required.

In this configuration all network services may be used, including the enterprise DHCP server. A DHCP server on the network may provide not only the terminal’s IP address, but also the location of the file server containing the software updates.
