1 Chapter 1 Introduction This Chapt er provides an overvi ew of the Wir eless Gatew ay's features and capabilities . Congratulations on the purch ase of your new Wireless Gateway Multi-Function Wireless Gateway .
W ireless Gateway User Guide 2 • Multi Segment LAN Support. LA Ns contain ing on e or more segm ents are supported, via the Wireless Gatew ay's built- in static routing table. If NA T (Network A ddress T ransla- tion) is disabled, the Wireless Gateway will fun ction as a static router.
Introduc tion 3 A dvanced Internet Functions • Virtual Servers. This feature allow s Internet users to access Internet se rvers on y our LA N. T he required se tup is quick an d easy. • User-Defined V irtual Servers. Internet us ers can access n on-standard In ternet Servers on your LAN by using this fe ature .
W ireless Gateway User Guide 4 NA T Firewall Protectio n The firew all pr otection provided b y th e Wireless Gateway is an intrinsic side effect of NAT (Netw ork Address T ranslation). A ll users on th e LAN sh are a single external IP address. From the extern al viewpoin t, there is no netw ork, only a sing le device.
Introduc tion 5 Wireless On - Wireless connection available; Wireless Access Point is ready f or use. Off - No Wireless con nection available. Flashing - Data is transmitted or received via the Wireless access point. This includes "netw ork traffic" as w ell as user data.
W ireless Gateway User Guide 6 Reset Button This button has three (3) functions : • Reboot . When pressed and released, th e Wireless Gateway w ill reboot (restart). • Diagnos tic print-out . If held d own for 3 seco nds, a dia gnostic print-out w ill be sent to the attached printer.
Introduc tion 7 DIP Switches DIP Swit ch Settin g Description 1=off 2=off Normal Operation . 1=off 2=on DHCP Server functio n disab led . 1=on 2=off Used to restore Def ault IP Address and clear Passw ord (See below ).
