Before IPSec can be used as a VPN service, a number of items must be created. This blog will show you what is needed to get started.

Introduction
Before IPSec can be used as a VPN service, a number of items must be created, including the following:
-A user account with administrator privileges
-A virtual private network (VPN) server running Windows Server 2008 R2
-A network router or firewall that supports IPSec
-A client computer running Windows 7 or Windows 8
The first step is to create a user account with administrator privileges. This account will be used to log in to the VPN server and create the necessary configurations. Next, a VPN server running Windows Server 2008 R2 must be created. This can be done using the Add Roles and Features Wizard in Server Manager.
Once the VPN server has been created, a network router or firewall that supports IPSec must be configured. This is necessary in order to allow communication between the VPN server and client computers. Finally, a client computer running Windows 7 or Windows 8 must be created. This computer will be used to connect to the VPN server and access resources on the network.
What is IPSec?
IPSec is a suite of protocols developed by the Internet Engineering Task Force (IETF) to provide authentication and encryption for Internet Protocol (IP) communications. The suite can be used with most IP networks, including the public Internet, to securely exchange data between two or more sites.
Before IPSec can be used as a VPN service, a virtual private network (VPN) must be created. A VPN is a private network created using public infrastructure, such as the Internet. A VPN allows two or more sites to securely exchange data over the Internet.
Creating a VPN requires two components: a VPN gateway and a VPN client. The VPN gateway is a hardware or software appliance that connects the VPN client to the IPSec network. The VPN client is software that runs on the user’s computer or mobile device.
The VPN gateway and the VPN client use IPSec protocols to authenticate each other and to encrypt and decrypt the data being exchanged between them. Data that is not encrypted is considered insecure and can be intercepted by anyone on the network. Data that is encrypted cannot be read by anyone who does not have the encryption key.
IPSec provides several security features, including data confidentiality, data integrity, and data authentication. Data confidentiality ensures that data cannot be read by anyone who does not have the encryption key. Data integrity ensures that data cannot be modified without detection. Data authentication verifies that data has not been tampered with and comes from a trusted source.
IPSec is an important security protocol for protecting information exchanged over IP networks. It is often used in conjunction with other security protocols, such as Transport Layer Security (TLS) or Secure Sockets Layer (SSL), to create a secure connection between two or more sites.
What is a VPN?
A VPN is a Virtual Private Network. A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. The VPN uses “virtual” connections routed through the Internet from the business’s private network to the remote site or employee. By using a VPN, businesses ensure security — anyone intercepting the encrypted data can’t read it.
To create a VPN, businesses first need to set up a network infrastructure, which usually consists of routers, switches, and other networking equipment. Once the infrastructure is in place, businesses can install and configure IPSec, which is software that enables two devices to connect and exchange data securely.
How IPSec Can Be Used as a VPN Service
IPSec can be used as a VPN service to allow secure communication between two or more networks. Before IPSec can be used, however, a VPN gateway must be created. This gateway will act as an intermediary between the networks and will encrypt and decrypt the data passing through it.
Creating an IPSec VPN
Before IPSec can be used as a VPN service, an IPSec tunnel must be created. This can be done using either a software client or a hardware appliance. Once the tunnel is created, each end of the tunnel must be configured with an IPSec policy.
Configuring the VPN Server
To configure the VPN server, you will need to:
– create a certificate request
– generate a self-signed certificate
– create an IPSec policy
– configure the VPN server
Configuring the VPN Client
In order for IPSec to be used as a VPN service, the following must be created:
-A user account that will be used to authenticate to the VPN server. This can be done through the Control Panel > User Accounts applet.
-A group account that will contain the user accounts that will be allowed to access the VPN server. This can also be done through the Control Panel > User Accounts applet.
-A shared key between the VPN client and server. This is typically done through a pre-shared key (PSK) or an Internet Key Exchange (IKE) certificate.
-An access control list (ACL) on the VPN server that specifies which users or groups are allowed to connect to the server. This is typically done through the router’s web interface.
Once these items have been created, IPSec can then be configured on the VPN client and server.
Testing the VPN Connection
After configuration, it is important to test the VPN connection to verify that it has been set up correctly. To do this, open the FortiGate unit GUI and go to Monitor > IPsec Monitor. The IPsec Monitor shows the status of all currently active tunnels and can be used to test and debug VPN tunnels.
Conclusion
To recap, in order to use IPSec as a VPN service, you must create two security policies: one for inbound traffic and one for outbound traffic. You also need to generate a shared key, which will be used to encrypt and decrypt data sent between the two VPN endpoints.
