ZyAIR B-2000 Wireless LAN Gateway with 4-Port Switch
1-2 Getting To Know Your ZyAIR
Wireless LAN MAC Address Filtering
MAC Address Filtering together with ESSID (Extended Service Set IDentifier), WEP (Wired Equivalent
Privacy) and IEEE 802.1x to ensure wireless network security.
IEEE 802.1x for Network Security
Your ZyAIR supports the IEEE 802.1x standard that works with the IEEE 802.11 to enhance user
authentication. With the local user profile, the ZyAIR allows you to configure up 32 user profiles without a
network authentication server. In addition, centralized user and accounting management is possible on an
optional network authentication server.
EAP (RFC2284)
EAP (Extensible Authentication Protocol) supports multiple authentication methods to ensure the highest
security level available.
RADIUS (RFC2138, 2139)
RADIUS (Remote Authentication Dial In User Service) server enables authentication, authorization and
accounting for your wireless network.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their
existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the
ZyAIR is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual computers.
PPTP Support
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using a TCP/IP-based network.
PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the
Internet. Use PPTP to connect to a broadband modem to achieve access to high-speed data networks via a
familiar "dial-up networking" user interface.
NAT for Single-IP-address Internet Access
The ZyAIR's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a
single IP account. NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the
host to be more easily accessible from various locations on the Internet. You must register for this service
with a Dynamic DNS client.
