Migration/Configuration IPv6

Unanswered Question
Feb 16th, 2010

Hi I am migrating from IPv4 to IPv6, my current configuration of my Internet router is:

access-list 50 permit 192.168.100.0 0.0.0.255

interface FastEthernet0
description ***WAN***
ip address 190.119.172.200 255.255.255.248
ip nat outside
speed 100
full-duplex

interface Vlan1
description ***LAN***
ip address 192.168.100.1 255.255.255.0
ip nat inside

ip nat inside source list 50 interface FastEthernet0 overload

ip route 0.0.0.0 0.0.0.0 190.196.17.201

My new addressing network IPv6 is: IPv6: 2800:160:18ff:0:0:0:0

I need enter this commands?:

ipv6 cef
ipv6 unicast-routing

ipv6 route ::/0  fastethernet0

interface fastethernet0

ipv6 address 2800:160:18ff:2/64

interface Vlan1
ip address 192.168.100.1 255.255.255.0

Is that correct?
How is the NAT configuration con inside ipv4 and outside ipv6?
Thank you very much

I have this problem too.

Dear Thomas ,

I prefer to get another IPv6 /64 class for your internal network and configure the same on your VLAN sub interface .This way your network will become as Dual stack  and assigning EUI-64- IPv6 address to VLAN interface will help the users in your LAN to get IPv6 address automatically for IPv6 enabled hosts

interface vlan 1
ipv6 address XX:XX:XX::/64 eui-64

If you need to configure NAT between IPv6 and IPv4  please refer the attached slide and let mw know how it goes .

Please rate if this helps

Regards,

Haris
