[. . . ] The ZyAIR logs you out after five minutes of no management using the web configurator, so you then have to log in again. 9 ZyAIR G-4100 Figure 4 Web Configurator: Login Screen 3. 2 Internet Connection Wizard The Wizard Setup screens appear by default after login only the first time you access the ZyAIR and run the wizard. This first screen varies depending on the type of Internet connection you use. Select DHCP Client if your ISP did not assign you a fixed IP address. Click Next to continue to Figure 9. Figure 5 Internet Connection: DHCP Client 10 ZyAIR G-4100 Select Static IP Setting If the ISP assigned a fixed IP address. Enter the WAN IP address, subnet mask, gateway IP address and DNS server address(s) that your ISP assigned you. Click Next to continue to Figure 9. Figure 6 Internet Connection: Static IP Select PPPoE If the ISP uses PPPoE for your account (PPPoE simulates a dial-up connection). A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes) that can be sent in a packet- or frame-based network. The Transmission Control Protocol (TCP) uses the MTU to determine the maximum size of each packet in a transmission. Too large an MTU size may mean retransmissions if the packet encounters a router that can't handle that large a packet. Use the advanced wireless setup screen if you want to use WPA with a RADIUS server (see the User's Guide for details). Figure 9 Wireless Settings Click Next to continue. Select the WEP (Wired Equivalent Privacy) check box to have the ZyAIR encrypt data frames before transmitting them over the wireless network. Select 64 Bit or 128 Bit WEP encryption and enter a key of the length described in the field. 3. Use the third wizard screen to configure a backup e-mail server in the event that the subscriber's e-mail server is unreachable from the ZyAIR. Select No to not have the ZyAIR redirect email in the event that a subscriber's e-mail server is unreachable from the ZyAIR. Select Yes to have the ZyAIR redirect subscribers' e-mail to the designated SMTP server (must be reachable from the ZyAIR) in the event that the subscriber's own e-mail server is unreachable from the ZyAIR. E-mail recipients see messages as if they came from the subscriber's regular e-mail server not the "backup" e-mail server. When you select Yes, enter the e-mail (SMTP) server's domain name (up to 50 characters) or IP address. Figure 10 E-mail Service Setup Click Next to continue. Enter the port number (25, or between 2500 and 2599) for the mail server. 13 ZyAIR G-4100 4. Use this screen to set whether or not the ZyAIR authenticates users before allowing them to access the Internet. Select Yes to require the ZyAIR to authenticate subscribers before allowing Internet access. This wizard configures authentication and accounting settings for the ZyAIR's built-in local subscriber database. Use the advanced RADIUS setup screen if you want to configure the ZyAIR to use an external RADIUS server for accounting and authentication (see the User's Guide for details). Select No to allow Internet access for all subscribers without authentication. Click Next to continue. Figure 11 Authentication Service Setup 5. Use the next wizard screen to set up a billing profile for the ZyAIR to use when generating subscriber accounts. 14 ZyAIR G-4100 Select Time to Finish to allow subscribers a one-time login. Once a subscriber logs in, the system starts counting down the pre-defined usage even if the subscriber stops the Internet access before the time period finishes. [. . . ] It is highly recommended you change the default user name and password. Type your new user name and password in the Username and Password fields; type the password again in the Confirm field Click Get from my Computer to have the ZyAIR retrieve the date and time from your computer. Select All if you want to allow management of the ZyAIR from any IP address. Select Selected and type the IP address of a "trusted" computer to allow access to the ZyAIR web configurator from that computer only. If the computer you are currently using is not the "trusted" computer, you will not be able to access the ZyAIR web configurator again from your current computer. Figure 20 System Setting Click Finish to save your settings to the ZyAIR. [. . . ]
