8.9 Technical Reference

This section provides some technical background information about the topics covered in this chapter.
8.9.1

LANs, WANs and the Zyxel Device

The actual physical connection determines whether the Zyxel Device ports are LAN or WAN ports. There
are two separate IP networks, one inside the LAN network and the other outside the WAN network as
shown next.
Figure 83 LAN and WAN IP Addresses

8.9.2 DHCP Setup

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain
TCP/IP configuration at start-up from a server. You can configure the Zyxel Device as a DHCP server or
disable it. When configured as a server, the Zyxel Device provides the TCP/IP configuration for the
clients. If you turn DHCP service off, you must have another DHCP server on your LAN, or else the
computer must be manually configured.
IP Pool Setup
The Zyxel Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the
product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your
LAN computers.
