Hi,

theres an Cisco 1921er Router within an SEC Lic. My Provider does DUALSTACK on WAN (ipv4 and ipv6).

My Problem: Clients on GigabitEthernet0/1 can only via ipv4 on the Internet,by enable IPV6 it will not works

when disable ipv4 and actiate ipv6 on the client( e.g. like an MAC OS X PC) , then only google.de works....

maybe i may something wrong? Can someone help me please?

This are my IPs from the DHCP on Cisco .....


IPV6:Addresse: 2001:a61:20f8:c401:aa20:66ff:fe52:4e84 Prefix 64
IPV6:Addresse: 2001:a61:20f8:78bd:3de2:4de2:aed5:1c82 Prefix 64
Router IPV6___:fe80::669e:f3ff:fe57:b41
DNS :dns-server 2001:A60::53:1 (from ISP)
DNS:dns-server dns-server 2001:A60::53:2 (from ISP)

by checking ipv6 on Clientbrowser like Firefox (howismyipv6.com),, i also may get the following ipv6:
2001:A61:20F8:C401:34DF:A000:EFF4:2015

Hello,

can you try and add:

dialer-list 1 protocol ipv6 permit

to your configuration ?

And temporarily disable 'dialer-list 1 protocol ip list 101 ?

I have a feeling we are just missing a small detail...

Under the Dialer 0 configuration, can you try again and add the rapid-commit option:

ipv6 dhcp client pd NODE-PD rapid-commit

Hi,

I am curious to know what happens if the IPv6 access list are disabled, or if you just allow all IPv6 traffic in and out. Can you give that a try ?

permit ipv6 any any

in both access lists WAN_OUTSIDE_INv6 and WAN_INSIDE_OUTv6  ?

Hello,

I recreated the following setup:

R1 (IPv6 server) --> R2 (IPv6 client)

R2 (the client) got IPv6 addresses from R1 (the server) by just configuring the interfaces with the commands 'ipv6 address autoconfig' and 'ipv6 enable'. This setup assumes that your provider has configured stateless DHCP, Can you try to put just this on your interfaces:

interface GigabitEthernet0/1

ipv6 enable

ipv6 address autoconfig

interface Dialer0

ipv6 enable

ipv6 address autonfig

I am setting up stateful DHCP as well, I will let you know when I get this to work.

Hello,

in case your provider has configured stateful DHCP, the commands on your interfaces should be:

interface GigabitEthernet0/1

ipv6 enable

ipv6 address dhcp (try this with or without the 'rapid-commit' option

interface Dialer0

ipv6 enable

ipv6 address dhcp (try this with or without the 'rapid-commit' option

I got this working in my test environment; either way, since your provider is the DHCP server, you would not need to configure any DHCP server items on your router.

Give this a try and let me know what happens.
