First of all what is VPN." VPN " stand for Virtual Private Network .Next how it works and where it is used . VPN works when the IP Conficts and IP is conflict because we dont use the PUBLIC IP means the IP we use is may be used by onther Company or Branch then we use VPN it works in the MAC address principal means it doesnot work on the IP it works Over the IP . And COMPUTER ,INTERNET or INTRANET, DHCP is required for the VPN .
We can connect to branch office of the same office thru a vpn by using backbone network provided by a service provider. ISP will provide till customer premises and customer at both sites shud use routers (CPE) to connect to the provider network. Packets are transferred over the provider network as if it is a private network i.e packets from a specific customer are never forwarded to an interface of a router on the backbone network which is not configured for that VPN. Although data of many customers are forwarded on the backbone, the end user feels as if it is a private network.
The preliminary requirement is that u must order for a leased / dedicated line from ISP.
