Chapter 7 LAN Setup
7.6 LAN Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
7.6.1
LANs, WANs and the ZyXEL Device
The actual physical connection determines whether the P-660H-T1v3s 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.

7.6.2 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 P-660H-T1v3s as a DHCP server or disable it. When configured as a
server, the P-660H-T1v3s 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 P-660H-T1v3s 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.
