So i installed wireguard using this automated installer, and now i am trying to make the server more secure by using digitalocean firewall and i do not really know how to configure it,tried to setup DO firewall by only allowing ssh 22 port but after that the vpn connection does not allow me to access the web or do anything.Can anyone help me with setting up firewall to make the server more secure?

WireGuard uses a different port than SSH, so your firewall is blocking its traffic. You need to allow the UDP port used by your WireGuard server; the default is 51820.
