Dynamic Dns Support; Port Forwarding - ZyXEL Communications P-334WH User Manual

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 ZyXEL Device 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 ZyXEL Device 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 ZyXEL Device supports three logical LAN interfaces via its single
physical Ethernet LAN interface with the ZyXEL Device itself as the gateway for each LAN
network.
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).

Port Forwarding

Use this feature to forward incoming service requests to a server on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP
address of the desired server.
