Cisco 1921 Router, Internet client acces works only with ipv4

macgyver1988 · ‎10-03-2016

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?

by checking ipv6 on Clientbrowser like Firefox (howismyipv6.com),, i also may get the following ipv6:

Hmm why is Active Clients:0??? theres only a Cisco connected to the WAN PORT (EHWIC.VA-DSL-B, and GigabitEthernet0/1 ) connected with my MACOSX....., so one Client..

should there also being one? but why ZERO=?????

Hello,

stupid question maybe, but the only setup I know of is to have two different routers as DHCP server and DHCP client for IPv6.

Can you try and configure your GigabitEthernet 0/1 with just these IPv6 commands:

interface GigabitEthernet0/1

ipv6 address autoconfig

ipv6 enable

Georg Pauwen · ‎10-08-2016

Hello,

in addition to my previous post, check out these documents for different examples of IPv6 client configs:

it wont works

and on the client on my MAC which is connected to GigabitEthernet0/1, i have two 2001:...XXX.. IP Addresses, some FD00 Adresses,

Router adress is something which FE80..:XXX

But it DNS , theres only an ipv4 adresses 192.168.50.2 , but NO IPV6 Adress......

macgyver1988 · ‎10-08-2016

And yes, my ISP provides the DHCP Server....

macgyver1988 · ‎10-08-2016

maybe important:???

Georg Pauwen · ‎10-08-2016

Hello,

I hope this doesn't get too confusing...

I looked again at your original configuration. Is NODE-PD the name of the prefix delegation pool ? Try to add the following to your original config:

ipv6 dhcp pool NODE-DHCPV6

--> prefix-delegation pool NODE-PD lifetime 1800 60
dns-server 2001:A60::53:1
dns-server 2001:A60::53:2
domain-name soho.intern

and under the interface config:

ipv6 dhcp client pd NODE-PD

macgyver1988 · ‎10-08-2016

yes NODE-PD is the prefix delegation pool name.

sure? you mean IPV6 DHCP client pd NODE-DHCPV6 and not Node-PD

heres my config :

this config wont works .

by the way, My Client does get no DNS Adress in IPV6.....?????

Shall i use

ipv6 nd ra dns server FD00:1234:5678::1

on GigabitEthernet0/1...

with them it wont works.....

Do you have another ideas?

Georg Pauwen · ‎10-08-2016

Hello,

the interface facing your provider, Dialer0, should have this:

ipv6 address dhcp
ipv6 address autoconfig default
ipv6 enable
ipv6 dhcp client pd NODE-PD

The interfaces connected to your clients should have this:

ipv6 address NODE-PD ::1/64
ipv6 address autoconfig
ipv6 enable
ipv6 dhcp server NODE-DHCPV6

on my mac os client, now i dont have a IPV6 Adress like 2001:XXX , now missing...only FD00 Adresses availbility.....

Routers IPV6 is now FE80...xXX

DNS is
