If you select "Allow other network devices to connect to the VPN through the NAS", the network
device can access the VPN via the NAS. To enable this function, you must change the default gateway
on that other device. Using a Windows PC as an example:
1. Go to "Control Panel" > "Network and Sharing Center" > "Change adapter settings".
2. Right-click the connection icon and choose "Properties".
3. Select "Internet Protocol Version 4 (TCP/IP)" and click "Properties".
4. Choose "Use the following IP address" and change the Default gateway to the IP address of the
NAS that is operating the VPN Client service then click "OK".
Connect a VPN server via OpenVPN
The NAS also supports OpenVPN, which is an open-source solution for VPN services. It protects a
VPN's connection with the SSL/TLS encrypting mechanism. It is also available on Windows, Mac OS X,
Linux, Android and iOS.
To connect to a VPN server via OpenVPN, follow these steps:
1. Go to "QVPN Service" > "VPN Client".
2. Click "Add" > "OpenVPN" to connect to a VPN server.
3. Select the OVPN file (.ovpn) and click “Open”.
4. Enter the connection configuration settings, including the profile name, and the username and
password of the VPN server.
5. Click inside the required text field to import the certificate (ca.crt) exported from the OpenVPN
server.
6. Specify the subnet mask.
7. Select any of the following options, as required:
o Use the default gateway on remote network: This will allow all packets to be transferred via the
VPN server.
o Allow other network devices to connect to the VPN through the NAS: This will allow network devices
on the same LAN as the NAS to connect to the same VPN.
o Reconnect when the VPN connection is lost: This will automatically reconnect to the VPN server
when the connection is lost.
8. Click "Apply" to start.
o If you check "Use the default gateway on remote network", the default gateway on your NAS will
change to the VPN server’s default gateway.
o If you check "Allow other network devices to connect to the VPN through the NAS", the network
device can access the VPN via the NAS.
