FreeBSD 14 moved to netlink. I guess there're issues about source address
selection in kernel routing stack.

Presume you have public IPv4 address a.a.a.a on the loopback interface. May you
have a try `ping -S a.a.a.a example.org` ?

The `-S` option forces the source address to a.a.a.a. You can replace
`example.org` to any public address outside.
