Introduction
 Communication is very vital in any business
 Communication over the internet has become to much
insecure thus the introduction of VPN technology
 VPN has enabled lots of companies to maintain
reliable, fast, and secure communication when
communicating via internet.
 Other advantages of VPN are improved internet
security, extended geographic connectivity, cost
savings and scalability [1].

Scope of the proposed VPN network
This proposal have two phases of the
implementation of VPN network for SME
organizations
 Phase 1: client to site VPN technology
 Phase 2: Site to Site VPN technology

 Two Linksys LRT224 Routers
VPN server
Firewall
Dedicated ISP

Sydney 192.168.2.1 10.10.10.202 10.10.10.200 254

Security features and policies
 Security polices in a VPN network allows IP to
pass between two or more interfaces
 A policy-based VPN requires an IPsec type of
security policy
 Another feature which is utilized in this is a
firewall which is in form of a software installed in
the VPN server

VPN service implementation
 An SME business needs to utilize a phased
approach as indicated in the six steps
 Assessment
 Design
 Testing
 Implementation
 Training
 Project management [3]
