wireguard if_wg manual page is missing? How to use?

[Vasily Postnicov]

Hello.

I discovered that public key derivation in if_wg is not working
properly. You will need to apply the following patch:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252894 and reinstall
the kernel (I tested it with Mullvad VPN).
Then you must create WireGuard interface like so:
ifconfig wg0 create private-key <Your private key here> listen-port
12345 # 12345 is just a random unused port
Then add a peer (endpoint):
ifconfig wg0 peer public-key <Peer's public key> allowed-ips 0.0.0.0/0
allowed-ips <more allowed IPs> endpoint <Endpoint's IP:port>
Then assign IP addres to wg0:
ifconfig wg0 inet <Your IP address in private network>

After these steps wg0 should go up. Then configure your firewall and
add new routes as you wish. Here is my configuration for Mullvad:

Do not forget to patch the kernel, otherwise it will not work.
