Chapter 1 Getting To Know Your ZyXEL Device

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers)
to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The
ZyXEL Device has built-in DHCP server capability enabled by default. It can assign IP
addresses, an IP default gateway and DNS servers to DHCP clients. The ZyXEL Device
can now also act as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.

• 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 interface with the ZyXEL Device itself as the gateway for each
LAN network.

• IP Policy Routing (IPPR)

Traditionally, routing is based on the destination address only and the router takes the
shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to
override the default routing behavior and alter the packet forwarding based on the policy
defined by the network administrator.

• PPP (Point-to-Point Protocol) link layer protocol.
• Transparent bridging for unsupported network layer protocols.
• RIP I/RIP II
• IGMP Proxy
• ICMP support
• ATM QoS support
• MIB II support (RFC 1213)

Networking Compatibility

Your ZyXEL Device is compatible with the major ADSL DSLAM (Digital Subscriber Line
Access Multiplexer) providers, making configuration as simple as possible for you.

Multiplexing

The ZyXEL Device supports VC-based and LLC-based multiplexing.

Encapsulation

The ZyXEL Device supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC
1483 encapsulation over ATM, MAC encapsulated routing (ENET encapsulation) as well as
PPP over Ethernet (RFC 2516).

Network Management

• Embedded web configurator
• CLI (Command Line Interpreter)
• Remote Management via Telnet or Web
• SNMP manageable
