That probably would not be a very practical approach.  As if the "perminent"
ipv6 address is actually something that updates frequently this setting would
be lost.   For example, if you were using a anycast 6to4 tunnel with a dynamic
ipv4 address, your "permanent" address would change whenever your IPv4 address
changed.

use_tempaddr=2 definitely seems like the way to do it correctly.   There is
still the unknown, do I need to manually set firewall rules that block incoming
connection requests on the temporary address?   If so what is the best way to
do that?
