    Plan Your IPSec VPN Tunnel Setup

    Before you set up an IPSec tunnel, it's important that you decide the following factors and plan your IPSec tunnel set up successfully.
    1. Decide on Type of VPN: Site-to-Site or Remote Access
      The site-to-site VPN allows using the IPSec security method to create an encrypted tunnel from one customer network to a remote site of the customer. However, the remote access VPN allows individual users to connect to a private network to access its services and resources.
    2. Select a Security Method for your VPN
      In site-to-site VPN, the IPSec security method is used to create an encrypted tunnel from one customer network to a remote site of the customer.
      In remote access VPN, individual users are connected to the private network.
    3. Decide on your VPN Client
      The site-to-site VPN does not need setup on each client. Remote access VPN may or may not need setup on each client.
    4. Decide on your VPN Tunnel Setup
      The site-to-site VPN does not require every user to initiate the VPN tunnel setup. Remote access VPN requires every remote access user to initiate the VPN tunnel setup.
    5. Decide on your Security Technology
      While site-to-site VPN supports IPSec technology, Remote access VPN supports SSL as well as IPSec technology.
    6. Decide if you wish Single or Multiple Users on your VPN
      In site-to-site VPN, multiple users are not allowed; In remote access VPN, however, multiple users are allowed.
