2.3 LAN TCP/IP and DHCP Server

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.

What is Static Route

When you have several subnets in your LAN, sometimes a more effective and quicker way for

connection

is the

Static routes

function rather than other method. You may simply set rules to

forward data from one specified subnet to another specified subnet without the presence of

RIP.

What are Virtual LANs

You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the

communication between different groups, please set up rules in Virtual LAN (VLAN) function

and the rate of each.
