====== IPv6 Support ======
With Software version [[ftp://share.netmodule.com/system-software/4.6/4.6.0.100/|4.6.0.100]] we started IPv6 Integration. Currently we support ipv6 on WAN only

==== General====

Netmodule device only support global scope addresses, which basically means WAN/WWAN interfaces can connect to existing IPv6 infrastructure and are also useable in VPN Tunnel structures.

<WRAP center round important 100%>
Please notice as well as in IPv4, providers still blocking incoming connections on the boarder gateway in their IPv6 network. For this reason it not set and done to have a "real" public ipv6 address.

=== DualStack Mode===
The dualstack implementation provides complete ipv4 and ipv6 protocol stack and allows parallel operation on the same network interface. It has been integrated as "Transition Strategy" to provide a soft transition into the ipv6 address space.

Telekom has no available ipv6 DNS server address, which will automatically be assigned to the ipv6 client. You need to define public [[https://simulator.netmodule.com/dnsServer.php.html|DNS server]] addresses in our WEB GUI.

===== Setup IPv6 WWAN Interface =====

===1. define IP version===
We going to select "ipv6".

{{:configuration:ipv6-ip-version_.png?700|}}
===2. define ipv6 APN===
In this example we are using a SIM Card by "O2". The Provider has also ipv6 availablity on their typical APN "internet".

{{:configuration:ipv6-apn.png?700|}}

After the setting has been applied the interface is ready to use.
