VPN
Virtual Private Network (VPN) is a technology to allow device to create a tunneling connection to a server and
becomes part of the server’s network. The network transmission of the device may be routed through the
VPN server.
For some users, especially enterprise users, a VPN connection might be required to be established before
activate a line registration. The device supports two VPN modes, Layer 2 Transportation Protocol (L2TP) and
OpenVPN.
The VPN connection must be configured and started (or stopped) from the device web portal.
L2TP
To establish a L2TP connection, users should log in to the device web portal, open webpage [Network] >>
[VPN]. In VPN Mode, check the “Enable VPN” option and select “L2TP”, then fill in the L2TP server address,
Authentication Username, and Authentication Password in the L2TP section. Press “Apply” then the device
will try to connect to the L2TP server.
When the VPN connection established, the VPN IP Address should be displayed in the VPN status. There
may be the delay of the connection establishment. User may need to refresh the page to update the status.
Once the VPN is configured, the device will try to connect with the VPN automatically when the device boots
up every time until user disable it. Sometimes, if the VPN connection does not establish immediately, user
may try to reboot the device and check if VPN connection established after reboot.
OpenVPN
To establish an OpenVPN connection, user should get the following authentication and configuration files
from the OpenVPN hosting provider and name them as the following,
OpenVPN Configuration file:
