ZyWALL 2 Series User's Guide
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.
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.
PPPoE Pass-through
A computer on the LAN-side of the ZyWALL can initiate a PPPoE session independently of any PPPoE
sessions running on the ZyWALL itself. These ''bridged'' PPPoE sessions are not restricted to the number of
PPPoE sessions allowed on the WAN side.
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.
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 interfaces via its single physical Ethernet LAN interface with the
ZyWALL itself as the gateway for each LAN network.
