here's my default route to the ISP:

ipv6 route public ::/0 2001:XXXX:XXXX:300::1

Check the command below. Is this your output?

ASA1# show asp drop | include header

Unsupported IPV6 header (unsupport-ipv6-hdr) 10

IPv6 packets carrying the routing header are always blocked, without the need of any further configuration.

asa5510(config)# sh asp drop | include header

asa5510(config)#

..no output from that command.

thx-

Have you tried packet tracer?

don't think this is the problem at the moment.  i dont have any win hosts hooked up.  trying to access via ubuntu and a cisco 4500 switch behind the asa.
