Chapter 5 LAN Setup

Basic Home Station VDSL2 P8802T User’s Guide

Click Add Entries in the LAN Setup screen to display the following screen.

Enable IGMP Snooping

Enable IGMP snooping to have the VDSL Router passively learn memberships in 
multicast groups.

Select Standard Mode to have the VDSL Router forward multicast packets to a port 
that joins the multicast group and broadcast unknown multicast packets from the 
WAN to all LAN ports.

Select Blocking Mode to have the VDSL Router block all unknown multicast 
packets from the WAN.

Disable DHCP Server

Select this to have the VDSL Router not provide DHCP services. Users must 
configure LAN devices with manual network settings if you do not have another 
DHCP server on the network.

Enable DHCP Server

Select this to have the VDSL Router serve as the DHCP server for the network to 
assign IP addresses and provide subnet mask, gateway, and DNS server information 
to LAN devices.

Start IP Address

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

End IP Address

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

DHCP Server Lease 

Time

Specify for how many hours to assign an IP address to a LAN device before making 
it available for reassignment to other systems.

Static IP Lease List

Use this table to assign IP addresses on the LAN to specific computers based on 
their MAC Addresses. 

MAC Address

The MAC (Media Access Control) of a LAN device to which the entry’s IP address is 
assigned.

IP Address

This field displays the IP address reserved for the LAN device with the entry’s MAC. 

Remove

Select entries and click the Remove Entries button to delete them.

Add Entries

Click this button to create a new static IP lease entry.

Obtain DNS info from 
WAN

Select this to have the VDSL Router get the Domain Name System (DNS) server 
addresses from the VDSL Router’s WAN interface.

Use Static DNS IP 
address

Select this to have the VDSL Router use the DNS server addresses you configure 
manually.

First DNS Server, 

Second DNS Server

Enter the first and second DNS (Domain Name System) server IP address the VDSL 
Router passes to the DHCP clients. 

Configure the second IP 
Address and Subnet 
Mask for LAN interface 

Select the check box to use IP alias to configure another LAN network for the VDSL 
Router. 

IP alias partitions a physical network into different logical networks over the same 
Ethernet interface. The VDSL Router supports multiple logical LAN interfaces via its 
physical Ethernet interface with the VDSL Router itself as the gateway for the LAN 
network. You can also configure firewall rules to control access to the LAN's logical 
network (subnet).

IP Address

Enter the second LAN IP address of your VDSL Router in dotted decimal notation.

Subnet Mask

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

Apply/Save

Click this button to save your changes.
