6.4 Technical Reference

The following section contains additional technical information about the ZyXEL
Device features described in this chapter.
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.

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.
