Sorry for the possible hijack.
Can someone educate me or point me to documentation on how NetBSD (or
possibly anything else) uses these various IPv6 addresses from
"myself" outward?
I play with IPv6 a little. I set up ipsec between 2 machines using
their SLAAC address which stayed stable. If I set up some other
listener I probably would want to use that address as well, or some
other permanent address.
But if I want to, say, browse the internet from one of those machines,
I think I want the outbound connection to be initiated from a
temporary address.
How does the OS decide?
