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 ::210.55.12.1 - I know the above is not likely to answer AAAA requests, but I plan to use DNS-ALG domain-name local.arpa 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
