10 3 Web Configura tion The Wireless Gateway must be configured through its built - in Web - based configuration utility. Before attempting to access this utility, note the following factory defaults: • WAN interface defaults: IP address 192.168.100.
11 Note: If the operating system or the browser is set to use an HTTP proxy server, either turn off the setting or put the Wireless Gateway's IP address in the list of unproxied hosts. 3. Power up the Wireless Gateway and wait about 15 seconds while it boots up.
12 Basic Setup The settings panels under the Basic Setup menu contain settings that almost always must be adjusted to let the Wireless Gateway operate at all.
13 Basic Setu p — Broadband Router The Basic Setup menu's Broadband Router panel is the first to appear whenever the configuration utility starts up. The controls in this panel are explained below. Router Name The Router Name is a text string that some ISPs require a s a means of identification.
14 The Local LAN settings are the IP address and subnet mask that will identify the Wireless Gateway to the other machines on you r LAN. The address must be unique on the LAN, that is, assigned exclusively to the Wireless Gateway; the subnet mask must be the same for all machines on the LAN that will communicate directly with the Wireless Gateway.
15 The Global WAN Mode controls must be adjusted as required by your ISP. The settings you enter here determine how the Wireless Gateway will be identified to your ISP's equipment and other machines on the global Internet. • If your ISP has given you a fixed IP address to use on the WAN link, click the Specify Global IP Address control.
16 server for the machin es on your LAN, it will pass the addresses to those machines as part of the automatic configuration process. (If the Wireless Gateway will not act as a DHCP server, you might need to set the DNS server addresses on each of the machines individually.
17 Basic Setup — Wireless AP The Wireless Gateway's “wireless AP” is the access point — the radio - frequency transmi tting and receiving circuitry — through which wireless devices will communicate with your LAN's wired devices and the Internet.
18 If the Wireless Gateway is the only AP on your LAN, it does not matter which channel you set the unit to use; properly configured 802.11b wireless stations will find the correct channel automatically. Where there are multiple APs with overlapping coverage areas, channel assignment must be carefully planned.
19 Basic Setup — Print Server To view and adjust the Wireless Gateway's print server settings, click Print Server in the command panel at the left edge of your browser window (if the com mand does not appear there, click Basic Setup at the top of the window first).
20 Machines running the Macintosh OS on your LAN can print on a PostScript printer attached to the Wireless Gateway. When such machines request information about network printers using the AppleTalk protocol, the Wireless Gateway will respond with the information shown in the Print Server panel.
21 Basic Setup — Admin Password It is highly recommended that you set an administrator password on the Wireless Gateway as soon as possible to prevent any tampering with the device's settings.
22 Advanced Settings Basic setup ensures that the Wireless Gateway will work with your ISP's equipment, your wireless stations, and your printer. Further adjustments are usually necessary to provide more sophisticated functions that may by desired or required on the local network.
23 Advanced Settings — DHCP Server The Wireless Gateway can act as a DHCP (Dynamic Host Configuration Protocol) server for machines on your LAN. It is a way to use private addresses in t he LAN when your ISP does not offer you enough globally legal IP addresses.
24 Enable Click No to turn the Wireless Gateway's DHCP server function off, or click Yes to turn t he function on. If you turn this function off, you can go directly to the bottom of the panel and click Save , ignoring the rest of the controls in the panel; they will have no effect on the Wireless Gateway's operation.
25 that the range of addresses must not contain the IP address you have already given to the Wireless Gateway. The From and To addresses always begin with the same three numbers as the Wireless Gateway's Local LAN address (see “Broadband Router” under “Basic Setup,” above).
26 twelve hexadecimal digits with or without spaces in between. The hexadecimal digits are 0 through 9 and A through F (in upper or lower case); 0080C82F8086, 0080c82f8086, 0080C8 2 F8086, and 00 80 C8 2F 80 86 are all different ways of writing the same MAC address.
27 Advanced Settings — Port Forwarding A TCP “port” is a number associated with a protocol providing a specific service. The source and destination port numbers are the first parts of a TCP packet. Port forwarding is often used in conjunction with Network Address Translation (NAT).
28 TCP Port to IP Forwarding This is a table of up to sixteen entries. A lis t of standard, commonly used TCP port numbers appears next to the table to help you create entries.
29 DMZ Host A DMZ host is a machine exposed to the Internet and running software desi gned to provide specific services while protecting the LAN's other machines from direct access from outside.
30 Advanced Settings — Port Open The Port Open function is provided mainly to facilitate controlled Internet gaming. It lets you specify the TCP ports that are used for input and output by up to sixteen applicati ons.
31 The Application section of the Port Open settings panel contains a number, a Name input bo x, and Save and Cancel buttons. The number is the number of the application for which Port Open settings currently appear (see “Go to,” above). The Name box helps you identify the application that the displayed settings are for.
32 to specify a range, click the Start Port box and type the lowest number of the range, and then click in the End Port box and type the highest number. The Add button is for sending the displ ayed I/O, Start Port, and End Port settings to the Wireless Gateway for storage in non - volatile memory.
33 Advanced Settings — Routing Routing settings determine whether the Wireless Gateway acts as a router, and how it interacts with other routers for efficient dispatching of packets to other networks.
34 A static route is a known, unchanging path from your LAN to another network or subnet. You can set up to sixteen static routes on the Wireless Gateway. A static route consists of the settings described below. IP Address: This is the IP network address of an outside network or subnet.
35 The LAN Interface settings control whether and how the Wireless Gateway uses RIP with any routing devices networked to it through its LAN p orts. • The TX setting controls the transmission of routing information to such devices.
36 After making sure all settings in the Routing settings panel are correct, click Save to store the settings in the Wireless Gateway's non - volatile memory. You can, alternatively , click Cancel (or simply exit the panel) to restore all settings in the panel to the values last saved to or retrieved from the Wireless Gateway.
37 Advanced Settings — Filters The Filters settings panel can be used to ensure that certain machines on the LAN cannot access the WAN; to ensure that certain protocols cannot be used by anyone on t.
38 Users Filter The Users Filter table lists machines on the LAN that are not allowed to access the WAN at all. There is room for sixteen entries. An entry can consist of an IP address or a MAC address, or both. (If both are e ntered, the Wireless Gateway will block all packets with either one, regardless of whether the other is associated with it.
39 The Protocols Filter control lets you list the TCP port numbers for up to sixteen protocols that you do not want LAN users to use over the WAN connection. A list of standard, commonly used TCP port numbers appears next to the table to help you create entries.
40 After making sure all settings in the Filters settings panel are correct, click Save to store the settings in the Wireless Gateway's non - volatile memory. You can, alternatively, click Cancel (or simply exit the panel) to res tore all settings in the panel to the values last saved to or retrieved from the Wireless Gateway.
41 Advanced Settings — Manager Console A “manager console” is a computer running Manager Server, a program designed to enhance the capabilities of devices such as the Wireless Gateway and can be found in the DC - ROM that comes with the Wireless Gateway.
42 Manager Console To communicate with a manager console, the Wireless Gateway must know the manager console's IP address. If you have set up a manager console, click in the IP Address box and type the address in. If no manager console exists, make sure the manager console IP Address control is set to 0.
43 to filter (that is, bloc k) connections that meet criteria you set. For full details, see the Manager Server user's guide. The default setting of the Log and Filter control is Disable . This setting ensures that the Wireless Gateway will not send information about network activity to the manager console for logging or filtering.
44 Separate connection periods with commas; do not type any other characters, not even spaces. The Holiday Table is for specifying days of the year when the Wireless Gateway should not connect to the WAN at all. Cl ick in the input box for the desired month and type the day or days of that month on which connection is not allowed.
45 Advanced Settings — Wireless Access The Wireless Access panel lets you contr ol which machines can, and which ones cannot, connect to the network through the Wireless Gateway's wireless access point. Initially, no controls are placed on wireless access through the Wireless Gateway.
46 MAC address is 0080C82F8086, w hich may also be written as 0080c82f8086, 0080C8 2F8086, or 00 80 C8 2F 80 86. The first step in creating a User List entry is to click in the MAC Address input box and type the station's MAC address, with or without spaces.
47 Advanced Settings — Wireless Encryption Wireless network communications are easily intercepted. WEP (Wired Equivalent Privacy) is an encryption method specified by the IEEE 802.11b standard to make any intercepted commun ications extremely difficult to interpret by unauthorized parties.
48 wireless devices to communicate through the Wireless Gateway, their encryption settings must be the same as the Wireless Gateway's. Input Format The Input Format control determines how your input for Key 1 through Key 4 will be interpreted by the Wireless Gateway when you save the settings in the W ireless Encryption panel.
49 This control determines which key the Wireless Gateway will use when WEP encryption is enabled. Click the list box to open it, and then drag to or click the name of the desired key.
50 Advanced Settings — Wireless Bridge The “wireless bridge” is the circuitry tha t transfers packets between the wireless access point and wired connections. The purpose of the Wireless Bridge settings panel is to prevent specified kinds of packets from passing across this bridge.
51 Protocol Filters Protocol filters prevent specified kinds of packets from passing in either direction across the wireless bridge. The Protocol Filters section of the Wireless Bridge panel c ontains controls for turning this function on and off and for selecting the filter or filters you want to use.
52 Unlike protocol filters, the Broadcast/Multicast Filter function is one - way: it prevents broadcast packets (those addressed to all stations on the network) and multicast packets (those addressed to two or more, but not all, stations) from passing through the wireless bridge from the wired segment to the wireless segment.
53 or 00 80 C8 2F 80 86. To list a station, find its MAC address, click in a MAC Address box, and type the address, with or without spaces. Save/Cancel After making sure all the controls in the Wireless Bridge setti ngs panel are set as desired, click Save to store the settings in the Wireless Gateway's non - volatile memory.
