A Virtual Private Network (VPN) extends a private network across a public network, such as the Internet. It enables a computer or network-enabled device to send and receive data across shared or public networks as if it was directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols or traffic encryption. SimpleWAN devices allow you to implement an IPsec VPN.
Within this section you will need to configure the following settings for IPSEC:
You can enable or disable PPTP from here, and get the Dial In address. Unless you have VPN users, you should disable this for security.
Here you can see the list of VPN users, and add new users.
IPSEC VPN can be used to create a Tunnel between devices. IPSEC settings must match on both units. For units that do not match (i.e. SimpleWAN unit to Cisco or Sonicwall) the settings between each unit is even more crucial.
Tunnels are commonly affected by connection issues such as Latency and Packet Loss. It is advisable to run a 48 Hour Intensive Latency Test on site prior to setting up a Tunnel to ensure that the tunnel will have good stability.
The L2TP feature is recommended over PPtP access being that it is more secure. Simply enable the L2TP server as well as the IPsec server. Create a user on the L2TP page, and configure the L2TP settings. It is recommended to configure with the highest options for both Encryption and Hash algorithms. MAC's have a built in client that needs no configuration changes. If you are using a Windows computer there is a registry change that will need to be applied prior to connecting. A link to a Windows form is pasted below that will document this process.
