It is assumed that each site will have its own access control, NAT and firewall policies.It is assumed that users will access Internet locally from their site router which acts as the default gateway, provides NAT and IP addressing via DHCP.Will need 5 tunnels for each each site, see the below diagram.
IPSec also has several hash methods to choose from, each giving different levels of protection.Įach site will need to establish a peer IPSec tunnel with all the other sites. IPSec has a choice of transform sets so that users may choose the strength of their data protection. This solution requires a standards-based way to secure data from eavesdropping and modification. Encapsulating Security Payload (ESP) RFC 4303.Dynamically generates and distributes cryptographic keys for AH and ESP. Internet Key Exchange (IKE) protocols.IPsec protocol suite can be divided in following groups: The IPSec standard provides a method to manage authentication and data protection between multiple peers engaging in secure data transfer.
Topology diagram and IP addressing scheme This document is made for the subject exercise for I0T’s Do It Yourself.
This document describes the proposed solution topology diagram, IP addressing scheme, the individual hardware requirements and their interconnections, software features, transport mediums, security and reliability. The same time meeting of most organization’s need. The reason these technologies are selected is I wanted to keep the solution simple and straight forward while at The proposed solution is using Mikrotik VPN router products. The solution design is based on the vendor best practices to build a site-to-site enterprise virtual private network (VPN). The solution proposes to deploy a site-to-site VPN on IP Security (IPSec) tunneling over Internet between the six remote sites and to provide a secure PPTP / L2TP service for remote users’ (Dial in VPN users) over Internet Networking Team applies the KISS principle wherever possible while balancing the needs of our organization.
