Administrator’s Guide for Yealink VC110 Video Conferencing Endpoint
104
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
