55 Chapter 1 Getting to Know Your ZyWALL
IEEE 802.1x for Network Security
The ZyWALL supports the IEEE 802.1x standard that works with the IEEE 802.11 to enhance
user authentication. With the local user profile, the ZyWALL 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.
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft.
Key differences between WPA and WEP are user authentication and improved data
encryption.
Wireless LAN MAC Address Filtering
Your ZyWALL can check the MAC addresses of wireless stations against a list of allowed or
denied MAC addresses.
WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.
Packet Filtering
The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.
Call Scheduling
Configure call time periods to restrict and allow access for users on remote nodes.
PPPoE
PPPoE facilitates the interaction of a host with an Internet modem to achieve access to high-
speed data networks via a familiar "dial-up networking" user interface.
PPTP Encapsulation
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. The ZyWALL supports one PPTP server connection at any
given time.
