i have a problem regarding an IPv6 ACL on a Cisco 2801. I run IOS Version 12.4(15)T3 Advanced IP Services. You will find below, what I put in my configuration.
My problem is that the outbound acl never matches anything. For example my tunnel broker pings the tunnel endpoint every 30 minutes i can see the echo requests in TU0-INBOUND. If i ping something i see the replies in TU0-INBOUND. But the match counters of TU0-OUTBOUND remain zero.
If i make a telnet like this 'telnet ipv6.google.com 80' i get '% Connection timed out; remote host not responding'. I would expect a match in line 3 of TU0-OUTBOUND and the router should create the temporary acl REFLECTOUT. But all what matches is the implicit deny of TU0-INBOUND causing the above time out. :-(
What am i missing here is it a bug or is there an error in my configuration?

The 'bug' i described above seems to apply only to packets the router generates itself. I tested it by creating a temporary subnet. Even though i had no end-to-end connectivity i could see packets matching the outbound acl which were created from a host on that subnet.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
