Description:

This document describes how to set up IPv6 NTPv6/NAT66 and Unique Local Addresses (ULAs) on LANCOM routers.


Requirements:

It is assumed that a working IPv6 internet connection has been established.


Scenario:

*) ULAs are defined in IPv6 as private addresses from the range fc00::/7 that are not routed on the Internet and can be used in private networks.

By default, a blocking route exists for IPv6 ULA addresses. If LANCOM access points or downstream routers (router cascade) are to be used in the LAN, the ULA blocking route in the IPv6 routing table (in the menu IP Router → Routing → IPv6 Routing Table) must be deleted on these devices.


Procedure:

1. Open the configuration with LANconfig and edit the configuration for the entry INTRANET in the menu IPv6 → Router Advertisement → Interface Options.

2. Activate the sending of router advertisements and set the announcement as default router to "Always".

3. Edit the table entry for INTRANET under IPv6 → Router Advertisement → Prefix list. If necessary, delete an existing table entry and create a new entry.

Configure the following values:

4. Create a new entry in the Firewall/QoS → IPv6 Rules → NPTv6 table.

Configure the following values:

5. In the menu IP Router → Routing → IPv6 Routing Table, make sure that an IPv6 default route is available.

6. Write the configuration back to the LANCOM router. The configuration is now complete.
