User manual BUFFALO WLAR-L11G-L SOFTWARE GUIDE

[. . . ] It supports data rates up to 11 Mbps in the basic mode with built-in firewall functions and is used as a multifunctional router/bridge between wired LAN and wireless LAN PCs. The WLAR-L11G-L incorporates features of high-end networking environments as well as home networking environments. Summary of the AirStation WLAR-L11G-L features: · Wi-Fi( (Wireless Fidelity) certified by the Wi-Fi Alliance. AirStation will communicate with other IEEE 802. 11b/Wi-Fi compliant wireless LAN products. [. . . ] 4. 7 Route Set communication routing between the WLAR-L11G-L and other network devices in the same network. Figure 4. 6 NAT Settings Figure 4. 7 Route Settings 4. 7. 1 Route Settings Set RIP information received by WLAR-L11G-L for each parameter. Select Both RIP1 and RIP2, RIP1, RIP2 or None (no RIP). 4. 7. 2 Add Routing Table Entry Set routing information. Destination address=Network IP address and the subnet mask for the destination. 11 Gateway=Address through which the packet passes before it reaches the destination address. Metric=Number of routers (1-15) to be passed before the packet reaches its destination. 4. 7. 3 Routing Table Entries (Display/Delete) Allows administrator to delete Routing tables. 4. 8 Packet Filter (Packet Filter Settings) Configures packet restrictions. 4. 8. 1 Setup for filtering · Action-If administrator selects Packet from LAN is Deny or Reject, the administrator will no longer have access to the AirStation configuration screens. This function prohibits setup from a wireless PC. The WLAR-L11G-L can be returned to the factory default settings (ALL of them!) by holding down the INIT button on the back of the unit for three seconds. Filtering is controlled by the following parameters: - Destination IP Address - Source IP Address - Protocol (all protocols, ICMP, arbitrary protocol number, TCP/UDP protocol number) - Destination port number - Log of filtering Click Add the rule. 4. 9 URL Filter Allows administrator to configure URL filter settings. If multiple keys are used, the order must match. For a 40bit WEP wireless card to communicate, all WEP must be limited to 40bit (104/128bit WEP may not be used). Examples of WEP key: 40bit ASCII: 5 digits of alphanumeric characters, "ab34Y" 104bit ASCII: 13 digits of alphanumeric characters, "123456abcdef7" 13 Figure 4. 10 Security/MAC Restrict Figure 4. 11 Security/ 802. 11b s Note: ASCII WEP is case sensitive. 40bit HEX: 10 digits, using characters 0-9 and a-f, "00234ABCDE" 104bit HEX: 26 digits, using characters 0-9 and a-f, "20123456789abcdeabcdewxyzh" Click Set. 4. 12 Security/RADIUS Select "Security", then "RADIUS" from the menu on the left. When a client requests communication with the WLAR-L11G-L, the WLAR-L11G-L reports its own MAC address to the RADIUS server Figure 4. 12 RADIUS Settings and asks for communication approval to the client. Once the RADIUS recognizes the client, the RADIUS issues a key to the AirStation and the client for initiation of communication. Clients must register with a RADIUS server on a network, before wireless authentication is possible. 4. 12. 1 RADIUS with MAC/EAP Authentication Set up the authentication by MAC address or EAP. If EAP authentication is selected, set the following parameters: - Server = Name of the RADIUS server or IP address. - Port = Number to be used by the RADIUS upon authentication. [. . . ] RJ-45 connector: An 8-pin connector used between a twisted pair cable and a data transmission device. ROM (Read Only Memory): Permanent memory. Router: Device that can connect individual LANs and remote sites to a server. Roaming: The ability to use a wireless device while moving from one access point to another without losing the connection. [. . . ]
