Chapter 1 Getting to Know Your ZyWALL 49
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.
Dynamic DNS Support
With Dynamic DNS (Domain Name System) 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 service provider.
IP Multicast
Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group
Management Protocol) is the protocol used to support multicast groups. The latest version is
version 2 (see RFC 2236); the ZyWALL supports both versions 1 and 2.
