Sure yes, see my explanation above.

Same answer. STUN, for some reason, can not open 2 consecutive ports on
your firewall. When the range is bigger, it has more changes to find 2
consecutive ports available, ie not already used.

If you don't trust me, just try capturing with ethereal on the router,
and see exactly what happens.
