3.2 LAN

Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design of

network structure is related to what type of public IP addresses coming from your ISP.

3.2.1 Basics of LAN

The most generic function of Vigor router is NAT. It creates a private subnet of your own. As

mentioned previously, the router will talk to other public hosts on the Internet by using public

IP address and talking to local hosts by using its private IP address. What NAT does is to

translate the packets from public IP address to private IP address to forward the right packets

to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that assigns

private IP address to each local host. See the following diagram for a briefly understanding.

In some special case, you may have a public IP subnet from your ISP such as

220.135.240.0/24. This means that you can set up a public subnet or call second subnet that

each host is equipped with a public IP address. As a part of the public subnet, the Vigor router

will serve for IP routing to help hosts in the public subnet to communicate with other public

hosts or servers outside. Therefore, the router should be set as the gateway for public hosts.

What is Routing Information Protocol (RIP)

Vigor router will exchange routing information with neighboring routers using the RIP to

accomplish IP routing. This allows users to change the information of the router such as IP

address and the routers will automatically inform for each other.

3.2.2 General Setup

This page provides you the general settings for LAN.

Click

LAN
