Remote User
Virtual Private Networks enable enterprise or small business customers to replace dial access ports with Internet connectivity via a Network Service Provider and gain access to global points of presence. VPNs for remote user dial access ensure that users can get network access by making a local call, which reduces both line charges and equipment costs by 60 percent or more.
The benefits to a company is the ability to reduce capital costs for purchasing and maintaining network hardware, telecommunications costs associated with maintaining multiple 800 numbers, and network management resources associated with maintaining this network for users.
The VPN options for remote users are either dial access outsourcing, (a Network Service Provider creates the VPN and security for the user with no or minimal intervention on the users part),global internet acces ( corporate users create a secure VPN tunnel for remote users), or high speed telecommuter (corporate users create a secure VPN tunnel for remote users using a cable modem).
