Chapter 1 Getting to Know Your ZyWALL

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 (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.

Your ZyWALL can check the MAC addresses of wireless stations against a list of allowed or 
denied MAC addresses.

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless 
network to help keep network communications private.

The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.

Configure call time periods to restrict and allow access for users on remote nodes.

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.

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.
