  • Page 70: Configuring Authentication Settings

    2.6. Configuring Authentication Settings The SMCWHSG44-G supports both IEEE 802.1x-based and Web redirection-based user authentication. Here is a brief description of how Web redirection works: When an unauthen- ticated wireless user is trying to access a Web page, a logon page is shown instead of the requested page, so that the user can type his/her user name and password for authentication.

  • Page 71: Aaa

    2.6.1. AAA 2.6.1.1. Basic Fig. 83. Web-Redirection Enabled with Authentication. There are three modes for Web redirection-Enabled with Authentication, Enabled without Authentication, and Disabled. In Enabled with Authentication mode, you have two options. Radius Authenticaion or Local Authentication built into the SMCWHS44-G. Currently for Radius Authentication EAP-MD5, PAP, and CHAP are supported.
  • Page 72 NOTE: Because your customized versions of authentication pages have to contain references to the SMCWHSG44-G's LAN IP address (192.168.2.1 by default). If the LAN IP address of the Wireless Hotspot Gateway is changed, you must remember to change the IP address references in your customized pages.

  • Page 73: Unrestricted Clients

    There are occasions on which you want some computers to be able to freely access the Internet without being authenticated first. For example, you may want your wired desktop computers connected with the SMCWHSG44-G to be uncontrolled while providing wireless Internet access service for your customers with wireless laptop computers.

    Internet by the host's domain name (e.g. http://www.smc.com), it first sends a DNS request to a DNS server on the Internet. The DNS request travels first to the SMCWHSG44-G, then the SMCWHSG44-G relays this request to the default gateway of the SMCWHSG44-G through a modem. Finally, this request is forwarded by the default gateway to the DNS server on the Internet.

  • Page 95 Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Encryption Data passing between the access point and clients can use encryption to protect from interception and eavesdropping.
  • Page 96 Infrastructure An integrated wireless and wired LAN is called an infrastructure configuration. Inter Access Point Protocol (IAPP) A protocol that specifies the wireless signaling required to ensure the suc- cessful handover of wireless clients roaming between different 802.11f-com- pliant access points. Local Area Network (LAN) A group of interconnected computer and support devices.
  • Page 97 Service Set Identifier (SSID) An identifier that is attached to packets sent over the wireless LAN and functions as a password for joining a particular radio cell; i.e., Basic Service Set (BSS). Session Key Session keys are unique to each client, and are used to authenticate a client connection, and correlate traffic passing between a specific client and the access point.

Wireless de-vices without a valid WEP key will be excluded from network traffic. WPA Pre-shared Key (PSK) PSK can be used for small office networks that may not have the resources to configure and maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared password for network access.
