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
