VIVOTEK - A Leading Provider of Multimedia Communication Solutions

User's Manual - 65

The NVR runs an OpenVPN client that makes remote connection via the RESTful (Repretational

State Transfer) API (Application Programming Interface) service to a VPN-enabled VAST server

running on the remote site. The applicable service port number ranges from 1 to 65534. The

default is port #3443. The NVR automatically registers with CA cert key and becomes a VAST

sub-station over a VPN tunnel. Once set, the VAST2 can automatically connect the NVR.

Note that on the side of the VAST server making connection via the OpenVPN, the server/client

conguration should be properly congured. On the mobile NVR, a proper gateway setting

should be made for VPN connection.

For the server conguration, the conguration le is placed in:

C:\Program Files (x86)\VIVOTEK Inc\VAST\Server\OpenVPN\cong\server\server.ovpn

You can edit your VPN IP subnet parameters according to your network configuration. The

Note that the NVR and VAST server should have a similar time setting when exchanging

certicate information. Otherwise, the mutual handshake authentication process may fail.
