[. . . ] INTRODUCTION 1. 1 AirStation Broadband Router Access Point (WBR-B11) Welcome to AirStation, the easy way to wireless networking. This book, which introduces you to the AirStation Broadband router access point, will help you connect to your network quickly. The AirStation Broadband Router Access Point (AP), WBR-B11, is a 4-port router wireless small/medium business (SMB) network device that complies with the IEEE 802. 11b standard on wireless LANs (Revision B). It supports data rates up to 11 Mbps in the basic mode with enhanced built-in firewall functions and is used as a multi-functional router/link between wired and wireless LAN PCs. [. . . ] · Metric - Number of routers (1-15) to be passed before the packet reaches its destination. Display/Delete Routing Table (Entries) - Allows administrator to delete routing information. Authorization - Authorization method for accessing the ISP PPPoE server. MTU (Maximum Transmit Unit) Size - Maximum Transmit Unit (578-1492) when using PPPoE. MRU (Maximum Receive Unit) Size - Maximum Receive Unit (578-1492) when using PPPoE. Keep Alive - Enables the PPPoE client to send a Link Control Protocol (LCP) echo request to the PPPoE server once per minute. Default Gateway - A default gateway IP should be assigned to the AirStation. Address Translation must be enabled for client PCs to connect to the Internet. Selecting Use enables the following functions: · IP Masquerade - When the LAN PC connects to the WAN side, the IP address of LAN PC is dynamically translated to become the WAN IP address of the AirStation. · Static IP address translation -When the WAN requests connection to the LAN, the WAN IP address of the AirStation is translated into the IP address of the LAN PC. Incoming packets containing no recognizable destination port information will be redirected to the DMZ's IP address. IP address of WAN - Select AirStation's IP address of WAN or Manual setting. For Manual setting, enter the IP address used by the WAN PC to connect to the local PC. Some network applications (online games or streaming software) require adding Address Translation tables). IP address of LAN - Select Manual and enter the destination IP address of the LAN PC; or select AirStations's IP address of LAN. If left blank, the packets are transferred to the same port number as the 13 13 Figure4. 3. 1A Routing Setup Figure4. 3. 1B Routing Setup Figure4. 3. 2A Address Traanslation Figure 4. 3. 2B Address Translation source port number. For Manual setting: · Operation - Packets from WAN (or LAN), select ignored, rejected, or accepted. IP Address - Filter for the specific IP address · Destination IP Address - The IP address for the packet to arrive at. Warning: If administrator selects Packet from LAN is Deny or Reject, the administrator will no longer have access to the AirStation configuration screens. The WBR-B11 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. Figure 4. 3. 3A Packet Filter Figure 4. 3. 3B Packet Filter Protocol - Mark and select a specific protocol. Select from all protocols, ICMP, arbitrary protocol number and TCP/ UDP protocol number. · TCP/UDP Destination Port - Select TCP or UDP, then enter port number. [. . . ] PPPoE (Point-to-Point Protocol over Ethernet): A specification for connecting users on an Ethernet line to the Internet through a common broadband medium. RADIUS (Remote Authentication Dial In User Service): A server that issues authentication key to clients. Repeater Hub: A device that collects, strengthens and transmits information to all connected devices, allowing the network to be extended to accommodate additional workstations. RC4: The encryption algorithm that is used in WEP. RJ-45 connector: An 8-pin connector used between a twisted pair cable and a data transmission device. [. . . ]
