ipv6 enable
ipv6 nd other-config-flag

The above config didn't work for me I had to create a new /64 via Clueless and add this here as an IP address
<pre>
# ipv6 nd prefix <your_slash_64>::1/64
</pre>
 
I would also add the following traffic-filter to the dialer interface
<pre>
# ipv6 traffic-filter outboundfilters-ipv6 out
</pre>
 
EDIT Feb 2015 - Alternative config below
 
<pre>
! Feb 2015 - Cisco 1841 / FTTC
! WAN
!
interface Dialer0
ipv6 address dhcp rapid-commit
ipv6 enable
</pre>
 
 
<pre>
# conf t
# ipv6 access-list ipv6 adsl-ipv6
# permit tcp any any established
# permit icmp any any
# deny ipv6 any any
# interface dialer0
# ipv6 traffic-filter adsl-ipv6 in
</pre>
 
ipv6 traffic-filter outboundfilters-ipv6 out
</pre>
 
If you include the "deny any any" line a "show access-lists ..." will show the number of
packets that have hit that line. Thus you can tell if a problem exists because
the packets are not passing through the access list or failure to communicate is
because of some other problem.
