Introduction1-2• Supports PPP dial-in connection using standard dial-up program• Easy setup through a Web browser on any operating system that supports TCP/IP• Compatible with all popular Internet applicationsApplicationsMany advanced applications are provided by the CheetahAccess Wireless Gateway,such as:• Flexible LAN AccessThe CheetahAccess Wireless Gateway provides connectivity to 10/100 Mbpswired devices as well as 11 Mbps wireless mobile users. The wireless interfacemakes it easy to create a network in difficult-to-wire environments, or to providequick access to databases for mobile workers.• Internet AccessThis device supports Internet access through an xDSL, Cable, ISDN or PSTNconnection. Since many DSL providers use PPPoE to establish communicationswith end users, the CheetahAccess Wireless Gateway includes a built-in client forthis protocol, eliminating the need to install this service on your computer.• Shared IP AddressThe CheetahAccess Wireless Gateway provides Internet access for up to 253users with a shared IP address. Using only one ISP account, multiple users on yournetwork can browse the Web at the same time.• Virtual ServerIf you have a fixed IP address, you can set up the CheetahAccess WirelessGateway to act as a virtual host for network address translation. Remote usersaccess various services at your site using a constant IP address. Then, dependingon the requested service (or port number), the CheetahAccess Wireless Gatewaycan route the request to the appropriate server (at another internal IP address).This secures your network from direct attack by hackers, and provides moreflexible management by allowing you to change internal IP addresses withoutaffecting outside access to your network.• User-Definable Application Sensing TunnelYou can define special applications that require multiple connections such asInternet gaming, videoconferencing, and Internet telephony. The CheetahAccessWireless Gateway can then sense the application type and open a multi-port tunnelfor it.• DMZ Host SupportAllows a networked computer to be fully exposed to the Internet. This function isused when the special application sensing tunnel feature is insufficient to allow anapplication to function correctly.
