How to use Wireguard

Drop a .conf file from your VPN provider into /config/wireguard and start the container. The file must have the name wg0.conf, or it will fail to start. In the qBittorrent web UI, go to Tools -> Options -> Advanced and set Network Interface to wg0. This instructs qBittorrent to only use the Wireguard network connection. This is important to prevent IP leaks.

Wireguard IPv6 issues

If you use Wireguard and also have IPv6 enabled, it is necessary to add the IPv6 range to the LAN_NETWORK environment variable.
Additionally the parameter --sysctl net.ipv6.conf.all.disable_ipv6=0 also must be added to the docker run command.
