Some additional notes below to compliment the official KB article for users new to Wireguard on how to configure the Windows client.
See the official KB with instructions for the router config: https://www.draytek.com/support/knowledge-base/7661#DrayOS5_section
In the example below we have a DrayOS5 router configured with a LAN address of 192.168.60.1 where you want to be able to access the network remotely (split tunnel).
Note the Wireguard client still needs to be installed, even if you are only intending on using the Draytek SmartVPN client. https://www.wireguard.com/install/
Clear text so you can copy/paste into your Wireguard client and update where necessary.
NOTE: As of writing, the Draytek SmartVPN client doesn't parse comments properly when importing a config file. Either remove the comment lines manually (every line starting with #) or use the Wireguard client to automatically remove them for you.
