If I understand correctly, developers of sing-box added ability to ping resources and see real ping instead of "<1 ms" in console and other places, if TUN is enabled
So my feature request - add ability to ping resources (at least) for direct connections, because some games and services shows wrong ping or can't ping at all, when TUN is enabled
