Pptp Encapsulation - ZyXEL Communications ZyWALL 2Plus User Manual

ZyWALL 2 Plus User's Guide
RADIUS (RFC2138, 2139)
RADIUS (Remote Authentication Dial In User Service) server enables user authentication,
authorization and accounting.
IEEE 802.1x for Network Security
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.
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.
