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
NOTICE! The device only supports non-encrypted basic authentication and
non-encrypted data tunneling. For users who need data encryption, please use
OpenVPN instead.
To establish a L2TP connection, users should log in to the device web portal, open page
[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 some 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 to the VPN automatically when the
device boots up every time until user disable it. Sometimes, if the VPN connection does not
established 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:
client.ovpn
CA Root Certification:
ca.crt
Client Certification:
client.crt
Client Key:
