OpenVPN is an open source software application that implements virtual private network
(VPN) techniques for creating secure point-to-point or site-to-site connections in routed or
bridged configurations and remote access facilities. OpenVPN uses a custom security protocol
that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators
(NATs) and firewalls.
OpenVPN allows remote users to authenticate for each other using a pre-shared secret key,
certificate, or username/password. When OpenVPN is used in a multi-client server
configuration, it allows the server to release an authentication certificate for every client via
signature and Certificate authority.
Below shows an illustration for successful OpenVPN tunnel established between Vigor router
(Main Office) and notebook (Remote User). The OpenVPN settings for both ends shall be the
same. Otherwise, the VPN connection is unable to establish successfully.
Note: Before configuring settings for OpenVPN, you should install SmartVPN Client
4.1.0.1 on your PC and latest firmware version on your Vigor router.
