IPv6 routing on a Cisco ASA 5500 Series device

[sthreei]

I have an external cisco router connected to the internet and and ASA 5510 behind that.  I have my tunnel setup on the external router.  I can ping from my ASA to my external router.  I can ping the outside interface of the ASA from the external router but I can't ping the inside interface of the ASA from the external router.  I can ping all the interfaces of the ASA from the inside network but I can't ping through the ASA to the external router.

These are the static routes and access-lists I have setup.

Any help or ideas would be greatly appreciated.

2001:xxxx:xxxx:2::2 is the IPv6 address of my internal router.
2001:xxxx:xxxx:1::129 is the IPv6 address of my external router.

ipv6 route inside 2001:xxxx:xxxx:100::/64 2001:xxxx:xxxx:2::2
ipv6 route inside 2001:xxxx:xxxx:101::/64 2001:xxxx:xxxx:2::2
ipv6 route inside 2001:xxxx:xxxx:105::/64 2001:xxxx:xxxx:2::2
ipv6 route inside 2001:xxxx:xxxx:255::/64 2001:xxxx:xxxx:2::2
ipv6 route outside ::/0 2001:xxxx:xxxx:1::129

Could you please post a (sanitized) version of the config files for your ASA and your external router?  I would like to take a look at how you have IPv6 enabled on the interfaces.

Interestingly, my layout is very similar.  I have a Cisco 871 connected to the Internet via DSL and like you am terminating my IPv6to4 tunnel using HE as my tunnel broker on the 871's tunnel0 interface.  I also have an ASA 5505 running 8.0(2) code and the Security Plus license inside the 871.

I have wireless clients who use the ASA 5505 as their default gateway and they're connecting to the Internet fine.

I noticed a couple of small differences between my config and yours.  One is that I have the "ipv6 address autoconfig" interface config command for all my IPv6 interfaces in addition to static IPv6 addresses.  I'm wondering if this might allow the ASA to discover neighbor IPv6 routers.  The other thing is that the ASA probably doesn't allow ICMPv6 redirects by default on its interfaces.  I'm speaking off the top of my head, but it wouldn't hurt explicitly allowing ICMPv6 on your ASA's inside interface, e0/1.  The command to do this is "ipv6 icmp permit any inside".  I'm thinking that if your internal router is the default gateway for hosts that the ASA might be refusing ICMPv6 redirects arriving on that inside interface.

Finally, one stupid question.  Is it just icmp that you're having trouble with?  Can hosts on the inside network connect to the Internet?

My inside hosts can only connect to the internet via IPv4 addresses not IPv6.  Thanks for your suggestions.  I'll try them and let you know if that works.

Does any one know what happened to this old topic??

If anyone knows, i'd like to find the answer. 

From what I see, the TEST ACL was not applied.

Thanks

I think you hit it on the head UltraZero. That's the only issue I see with the config.
