1-4 Getting to Know Your ZyWALL
administrator to define time periods and days during which content filtering is enabled and to include or
exclude a range of users on the LAN from content filtering.
Wireless LAN MAC Address Filtering
MAC Address Filtering together with ESSID (Extended Service Set IDentifier) and WEP (Wired Equivalent
Privacy) ensure the most secure wireless solution. This feature is not available on all models.
Brute-Force Password Guessing Protection
The ZyWALL has a special protection mechanism to discourage brute-force password guessing attacks on
the ZyWALL’s management interfaces. You can specify a wait-time that must expire before entering a fourth
password after three incorrect passwords have been entered. Please see the appendices for details about this
feature.

Packet Filtering
The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ZyWALL and other UPnP enabled devices can dynamically join a
network, obtain an IP address and convey its capabilities to other devices on the network. This feature is not
available on all models.
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.
1 Brute Force Password Protection was not available on every model at the time of writing.
