52 Chapter 1 Getting to Know Your ZyWALL
1.2.2.20 Call Scheduling
Configure call time periods to restrict and allow access for users on remote nodes.
1.2.2.21 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.
1.2.2.22 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.
1.2.2.23 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.
1.2.2.24 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.
1.2.2.25 IP Alias
IP Alias allows you to partition a physical network into logical networks over the same
Ethernet interface. The ZyWALL supports three logical LAN and/or DMZ interfaces via its
single physical Ethernet LAN and/or DMZ interface with the ZyWALL itself as the gateway
for each network.
1.2.2.26 IP Policy Routing
IP Policy Routing provides a mechanism to override the default routing behavior and alter
packet forwarding based on the policies defined by the network administrator.
