Chapter 1 Introduction 21Installing the BayStack Instant Internet Management Software Version 7.11IPX networksAn IPX network is automatically secure because there is no IP traffic on thenetwork. In this type of network, Instant Internet provides quick and easy accessto the Internet. On IPX networks with IPX workstations, Instant Internet supportsup to 250 application sessions.This means that IPX workstations can access theInstant Internet unit using up to 250 application instances.Services Instant Internet providesTable 1 describes the services that Instant Internet provides for IP networks.Table 1 Services Instant Internet providesService FeaturesAddressTranslationThe Address Translation service enables Instant Internet to act like a standard routerby routing IP information from one location to another. However, this service enablesInstant Internet to go beyond the simple routing role by translating illegal (reservedprivate) LAN workstation IP addresses into legal IP addresses.Address Translation supports the IPSEC ESP protocol.Client Login Instant Internet allows you to identify workstations for logging and access control.DHCP Server Using Instant Internet as a DHCP server allows you to set one option on eachworkstation, and then configure Instant Internet once.When you install Instant Internet, it determines whether or not you are running DHCPon your network. If not, then Instant Internet configures itself as a DHCP server. IfInstant Internet does not configure itself as a DHCP server and you want to use thisservice, you must enable it.DNS Proxy Server Instant Internet acts as a Domain Name Service (DNS) proxy server by translatinghost names into numerical IP addresses.IP Routing Instant Internet provides access to the Internet through IP routing. It maintainsrouting tables that help it determine the destination of data packets. This enablesnon-Windows workstations (Macintosh, UNIX, and OS/2) to access the Internetthrough Instant Internet as IP workstations.RemoteConfigurationYou can use a Telnet application and remote access commands to configure theInstant Internet unit from a remote location.
