Table 23 LAN > IP
LABEL 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
Starting
Address
This field specifies the first of the contiguous addresses in the IP
address pool.
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
from a WAN
interface
When a LAN client sends a DNS query to the P-870HN-51D, the P-
870HN-51D forwards the query to the system DNS server configured
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
Server
Enter the first DNS (Domain Name System) server IP address the P-
870HN-51D passes to the DHCP clients.
Second DNS
Server
Enter the second DNS (Domain Name System) server IP address the
P-870HN-51D passes to the DHCP clients.
IGMP Snooping
Enable IGMP
Snooping
Select this option to enable IGMP snooping. This allows the P-870HN-
51D to passively learn multicast group.
Standard
Mode
Select this to have the P-870HN-51D forward multicast packets to a
port that joins the multicast group and broadcast unknown multicast
packets from the WAN to all LAN ports.
