Configuring Network

The endpoint supports SSL VPN, which provides remote-access VPN capabilities through
SSL. OpenVPN is a full featured SSL VPN software solution that creates secure
connections in remote access facilities and is designed work with the
TUN/TAP virtual
networking interface. TUN and TAP are virtual network kernel devices. TAP simulates a
link layer device and provides a virtual point-to-point connection, while TUN simulates a
network layer device and provides a virtual network segment. The endpoint uses
OpenVPN to achieve the VPN feature. To prevent disclosure of private information,
tunnel endpoints must authenticate each other before secure VPN tunnel is established.
After the VPN feature is configured properly on the endpoint, the endpoint works as a
VPN client and uses the certificates to authenticate the VPN server.
To use VPN, the compressed package of VPN-related files should be uploaded to the
endpoint in advance. The file format of the compressed package must be *.tar. The
VPN-related files are: certificates (ca.crt and client.crt), key (client.key) and the
configuration file (vpn.cnf) of the VPN client. For more information, refer to
