Dynamic Dns Support; Central Network Management - ZyXEL Communications 35 Series User Manual

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, WLAN and/or DMZ interfaces
via its single physical Ethernet LAN, WLAN and/or DMZ interface with the ZyWALL itself
as the gateway for each network.
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.

Central Network Management

Central Network Management (CNM) allows an enterprise or service provider network
administrator to manage your ZyWALL. The enterprise or service provider network
administrator can configure your ZyWALL, perform firmware upgrades and do
troubleshooting for you.
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging
management information between network devices. SNMP is a member of the TCP/IP
protocol suite. Your ZyWALL supports SNMP agent functionality, which allows a manager
station to manage and monitor the ZyWALL through the network. The ZyWALL supports
SNMP version one (SNMPv1).
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).
