DESCRIPTION

LAN TCP/IP

 

 

 

Group Name

Select the interface group for which you want to configure the LAN

 

TCP/IP settings. See Chapter 19 on page 213 for how to create a new

 

interface group.

 

 

IP Address

Enter the LAN IP address you want to assign to your P-870HN-51D 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

 

 

 

Enable DHCP

Select this to have the P-870HN-51D act as a DHCP server or DHCP

 

relay agent.

 

Otherwise, deselect this to not have the P-870HN-51D provide any

 

DHCP services. The DHCP server will be disabled.

 

 

DHCP Server

Select this option to have the P-870HN-51D assign IP addresses and

 

provide subnet mask, gateway, and DNS server information to the

 

network. The P-870HN-51D is the DHCP server for the network.

 

When the P-870HN-51D acts as a DHCP server, the following items

 

need to be set:

 

 

IP Pool

This field specifies the first of the contiguous addresses in the IP

Starting

address pool.

Address

 

 

 

Pool Size

This field specifies the size, or count of the IP address pool.

 

 

DHCP Relay

Select this option to have the P-870HN-51D forward DHCP request to

 

the DHCP server.

 

 

Relay Server

If you select DHCP Relay, enter the IP address of the DHCP server.

 

 

DNS Servers Assigned by DHCP Server

 

 

Obtain DNS info

When a LAN client sends a DNS query to the P-870HN-51D, the P-

from a WAN

870HN-51D forwards the query to the system DNS server configured

interface

in the WAN interface you select.

 

If you do not configure DNS servers on the selected WAN inteface, the

 

P-870HN-51D uses the LAN IP address and tells the DHCP clients on

 

the LAN that itself is the DNS server.

 

 

Use the following Static DNS IP address

 

 

First DNS

Enter the first DNS (Domain Name System) server IP address the P-

Server

870HN-51D passes to the DHCP clients.

 

 

Second DNS

Enter the second DNS (Domain Name System) server IP address the

Server

P-870HN-51D passes to the DHCP clients.

 

 

IGMP Snooping

 

 

 

Enable IGMP

Select this option to enable IGMP snooping. This allows the P-870HN-

Snooping

51D to passively learn multicast group.

 

 

Standard

Select this to have the P-870HN-51D forward multicast packets to a

Mode

port that joins the multicast group and broadcast unknown multicast

 

packets from the WAN to all LAN ports.
