1. NAT-PT translation is not supported in Cisco Express Forwarding (CEF).
The CEF must be disabled by the command no ipv6 cef (see examples above).
2. It may be necessary to disable IPv6 redirects on the IPv6 interface taking part in the NAT-PT by the
command no ipv6 redirects (see examples above).
The reason for this is unclear. However, with the dynamic NAT-PT configuration above without
suppression of IPv6 redirects, the router very often (but not always) sent the ICMP6 redirect messages
to IPv6 KCS core host and thus instructing it to sent its IPv6 packets to a different router which was
completely wrong.
6.6 How to Set Up KCS for IPv6
Please consider following conventions when typing IPv6 addresses either during KCS setup, directly into
the Windows registry or in the KCS client configuration panels.
1. Whenever possible, enter the symbolic host name instead of the long IPv6 address, example:
2. If necessary to enter the IPv6 address without the port number, enter it simply in the same way as you
would enter the IPv4 address, for example:
or
3. If necessary to enter the IPv 6 address with the port number, enter it quoted with “[]” brackets followed
by the colon (:) and the port, for example:
4. In the case of entering own IP address for server listeners, use following conventions:
In order to listen on all IPv4 and IPv6 addresses on all interfaces, either leave the IP address field
empty, set it to 0.0.0.0 or ::0, for example:
or
or
In order to listen on particular IPv6 address, specify that address, for example:
