Quick poll:
When a 6to4 relay encapsulates v6 traffic and sends it to a 6to4 host
over v4, should the source address be 192.88.99.1 or the relay's v4
unicast address?
Stateful firewalls would prefer that the return traffic come from
192.88.99.1 (assuming they properly handle proto 41 traffic).
The scenario is 6to4 to 6to4.
I thought that was exactly the scenario Kevin was *not*
asking about. In that case it's obvious that each 6to4 box
will use its own IPv4 address as source (which is why it's
not mentioned in RFC 3056 - because it's obvious).
