I tried wireguard-go on OpenBSD and FreeBSD. I want to use WireGuard as replacement for OpenVPN point to point tunnels with dynamic routing (OSPF, iBGP). Especially this requires the right interface flags for the tun interface. So far wireguard-go on *BSD configures the tun interfaces as multicast incapable, broadcast interface which confuses the OpenBSD OSPF daemon completely and doesn't make any sense for a point to point tunnel. I get that wireguard-go tries to fake point to multipoint support that way. Is there a better solution than changing the hardwired argument ioctl() in tun/tun_*bsd.go?
