5 G ATEWAY C ONFIGURATION Navigating Through the Gateway Configuration Pages This chapter describes all the screens available thr ough the Gateway configuration pages, and is provided as a r eference. T o get to the configuration pages, browse to the Gateway by entering the URL in the location bar of your browser .
42 C HAPTER 5: G ATEWAY C ONFIGURATION ■ Status and Logs - displays the curren t status and activity logs of the Gateway . ■ Support - contains a comp r ehensive online help system Option T abs Each corresponding menu page may also provide sub-sections which are accessed through the use of tabs (see Figur e 27 for example).
Welcome Screen 43 Notice Board Figure 28 Notice Board Scr een The Notice Board is used to display configuration war ning messages. For example, you would be warned if you had disabled the Firewall.
44 C HAPTER 5: G ATEWAY C ONFIGURATION If you have forgotten your password you need to reset the Gateway . See “ Forgotten Password and Reset to Factory Defaults ” on page 76 Wizard Figur e 30 Wizard Screen Click WIZARD... to launch the configuration wizar d.
LAN Settings 45 The LAN Settings scr een is used t o specify the LAN IP address of your Gateway , and to configure the DHCP server . 1 Select Unit Configuration and t hen specify the Gateway IP Addre ss and Subnet Mask in the LAN Settings field. The default IP address of the Gateway is 192.
46 C HAPTER 5: G ATEWAY C ONFIGURATION As the IP address is fixed to a MA C addr ess, then each particular computer will normally be issued with the same IP address. The only time that a PC will get a differ ent IP address is if the unit is reset to factory defaults or the DHCP server has run out of IP addresses.
Wireless Settings 47 channel number . Usually the Wi r e less computers will scan to find the correct channel, but if they don't you must configur e them to use the same Channel number as the Gateway . V alid ch annels are country depen dent. See “ Channels ” on page 115 for a list of channels approved by each countr y .
48 C HAPTER 5: G ATEWAY C ONFIGURATION Encryption Figure 34 Encryption Scr een Wi r e d Equivalent Privacy or WEP allows you to encrypt th e traf fic between your W ireless PC and the Gate way . It is important to r emember that with WEP disabled anyone with a W ir eless PC can eavesdrop on your network.
Wireless Settings 49 Encryption Keys Figure 35 Encryption Keys Scr een A Key is a hexadecimal (0-9, A-F) num ber used to encrypt and decrypt the data. There can be up to 4 keys and each key can b e as long as 26 digits. The Gateway also offers a number of methods for converting plain text into hex keys.
50 C HAPTER 5: G ATEWAY C ONFIGURATION ■ Passphrase - This is another common method and similar to the 3Com Encryption string. In 64 bit WEP , the passphrase will generate 4 differ en t keys. However , in 128 bit WEP , this metho d only generates 1 key which is replicated for all 4 keys.
Wireless Settings 51 same Service Area Name/SSID, cha nnel and encryption settings as the Gateway can connect to it. Select Only Authorised W ireless PCs can connect to the Gateway to enable and configure this feature. If you enable this feature from a Wireless PC, it will automatically be added to the Authorised Wireless PC list.

Internet Settings 59 ■ Use this PC’ s MAC a ddress - This field is automatically filled in with the MAC address of the PC you ar e using to configure the Gateway . Y ou should use this address only if you were previously using this computer to connect directly to your modem.
60 C HAPTER 5: G ATEWAY C ONFIGURATION 6 Enter your PPP over Ethernet service name in the PPPoE Service Name text box. Not all ISPs requir e a PPPoE serv ice name. Only enter a se rvice name if your ISP r equires this. 7 Select an idle time from the Maximu m Idle Time drop-down list.
Firewall 61 6 Select an idle time from the Maximu m Idle Time drop-down list. This value will corres pond to the amount of idle time (no Internet activity) that will pass befor e the Gateway automatica lly ends your PPTP session. 7 IP settings must be used when establ ishing a PP TP connection.
62 C HAPTER 5: G ATEWAY C ONFIGURATION Virtual Server Activating and configuring a virtual server allows one or more of the computers on your network to function as a public server . For example, one of your computers could be configured as an F T P server , allowing others out side of your of fice network to download files of your choos ing.
Firewall 63 The port numbers are specified usin g a comma-separated list, with hyphens to denote port number rang es. So for example, en tering 2, 3, 5-7 would cause ports 2, 3, 5, 6, and 7 to be activa ted.

86 A PPENDIX B: I P A DDRESSING For your network to work correctly , all devices on the network must have: ■ The same sub-network ad dr e ss. ■ The same subnet mask. The only value that will be different is the specific host device number . This value must always be unique.
How does a Device Obtain an IP Addr ess and Subnet Mask? 87 This type of IP Address operates on a subnet mask of ‘255.255.0.0’. See Ta b l e 4 for an example about how a network (only four computers re pres ented) and a Gateway migh t be config ured.
88 A PPENDIX B: I P A DDRESSING an IP address at random fr o m th e industry standard subnet of 169.254.x.x (with a s ubnet mask of 255.255.0.0). If two devices allocate themselves the same address, the c onflict is detected and one of the devices allocates itse lf a new address.
