I'm trying to get NAT-PT support working on a Cisco DSL router to
support native ipv6 clients behind it. I've done a lot of searching,
and can't find the answers to what I'm doing wrong. I have two problems.

First, I can't get them to grab additional parameters from DHCP. I'm using:

ipv6 dhcp pool dhcppool
dns-server ::
- I know the above is not likely to answer AAAA requests,
but I plan to use DNS-ALG

Interface Ethernet0
ipv6 enable
ipv6 nd other-config-flag
ipv6 dhcp server dhcppool

The second problem is I can't NAT-PT to work at all. It doesn't even
attempt to do translations. Snippits I'm using are:

Interface Dialer0
description ipv4 Interface connecting to Internet
ipv6 nat

Interface Ethernet0
description ipv6 Interface connection to local lan (aka LINK-LOCAL)
ipv6 address 3FFE:AAAA:BBBB:1::9/64
- An address copied from an example, hope to use LINK-LOCAL
addresses later
ipv6 enable
ipv6 nat

ipv6 nat translation udp-timeout 600
ipv6 nat v6v4 source list pt-list1 interface Dialer0 overload
ipv6 nat prefix 3FFE:B00:1::/96
ipv6 access-list pt-list1
permit ipv6 3FFE:AAAA:BBBB:1::/64 any
