ZyXEL Communications P-312 Dynamic DNS Support, IP Multicast, IP Alias, Full Network Management

P312 Broadband Security Gateway

Dynamic DNS Support

With Dynamic DNS 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 client to use this service.

IP Multicast

Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way to deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236). Both versions 1 and 2 are supported by the Prestige.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the Prestige itself as the gateway for each LAN network.

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information between network devices. SNMP is a member of TCP/IP protocol suite. Your Prestige supports SNMP agent functionality, which allows a manager station to manage and monitor the Prestige through the network. The Prestige supports SNMP version one (SNMPv1).

Auto-negotiating 10/100Mbps Ethernet

The LAN interface automatically detects if it’s on a 10 or a 100 Mbps Ethernet.

Network Address Translation (NAT)

NAT (Network Address Translation - NAT, RFC 1631) allows the translation of an Internet Protocol address used within one network to a different IP address known within another network.

DHCP (Dynamic Host Configuration Protocol)

The Prestige supports DHCP Server and Client (RFC 2131 and RFC 2132). The Prestige's DHCP server capability allows you to automatically assign TCP/IP settings to a workstation on your LAN. The Prestige's DHCP client capability allows it to get automatically its IP address from the ISP on the WAN.

Full Network Management

This feature allows you to access SMT (System Management Terminal) through the console port or telnet connection.

RoadRunner Support

In addition to standard cable modem services, the Prestige supports Time Warner’s RoadRunner Service.

Time and Date Setting

This new feature (Menu 24.10) allows you to get the current time and date from an external server when you power up your Prestige. The real time is then displayed in the Prestige error logs and firewall logs. If you do
