It doesn't work because STUN reports different external IP address

I was under impression that rejects REGISTER only if Via
sent-by is in private address space (see [1,2]) but here Via sent-by
is public IP. My only guess is that compares Via sent-by and
received and rejects REGISTER if they don't match. May I ask why there
are such restrictions?
