Chapter 6 LAN Setup

P-870HW-51a v2 User’s Guide

The following table describes the fields in this screen.  

This table allows you to assign IP addresses on the LAN to specific individual 
computers based on their MAC Addresses. 

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC 
address is assigned at the factory and consists of six pairs of hexadecimal 
characters, for example, 00:A0:C5:00:00:02.

Table 14   LAN > IP

IP Address

Enter the LAN IP address you want to assign to your ZyXEL Device in 
dotted decimal notation, for example, 192.168.1.1 (factory default). 

IP Subnet Mask 

Type the subnet mask of your network in dotted decimal notation, for 
example 255.255.255.0 (factory default).

DHCP Setup
Active DHCP 
Server

Select this option to have the ZyXEL Device assign IP addresses and 
provide subnet mask, gateway, and DNS server information to the 
network. The ZyXEL Device is the DHCP server for the network.

Otherwise, deselect this to not have the ZyXEL Device provide any 
DHCP services. The DHCP server will be disabled. 

When the ZyXEL Device acts as a DHCP server, the following items 
need to be set: 

IP Pool Starting

This field specifies the first of the contiguous addresses in the IP 
address pool.
