To check if WireGuard Server is working properly
To check if WireGaurd Server is working properly, we can use another
device connected to another network and use the WireGuard configuration
we exported earlier to connect and see whether it connects properly and
whether the IP address is the IP of WireGuard Server.
The simpliest way is to use a cell phone with WireGuard official client
app installed, turn off its Wi-Fi connection, and only connect to Internet via
3G/4G/5G. Then open the WireGaurd app, import the WireGaurd
configuration from QR code. Enable the connection, check if the phone has
Internet access and whether its IP address is the IP of your WireGuard
Server.
There are several common reasons cause failed:
• The Internet Service Provider doesn't assign you a public IP
address, please check here.
• You may need setup port forwarding, please check here.
• The port you are using for WireGuard Server is blocked by the
Internet Service Provider, change to another port, or contact the
Internet Service Provider.
• Some countries/regions may block the VPN connection.
WireGuard Client App
We can use another GL.iNet router as WireGuard Client, or use their official
app on other devices with various OS.
• Please refer to WireGuard Official
