You seem to be fixed on the idea that a ipv6 stack has to have stateful
firewalling, or else its utter crap, correct? :-)
No, I'll try to say this clearer.
The stack works fine in. And out. But for a useful virtual circuit you must
have something like connection tracking.
Remember what my issue is:
- I have a very tight firewall,
- I ping6 out,
- The firewall blocks the reply back, because the connection is stateless!
- Same with http, etc.
This means that I have to open for incoming, virtually every port I send
outgoing to, or else I do not get any replies. This is what I call
non-functional, because one does not open incoming ports, for the most part.
Why are you not having this problem?
Connection tracking doesn't scale. It's impossible to hash the entire
Internet.
