Hello,
  This is to announce an experiment of nat64 on the ietf-nat64 SSID. We 
would like to thank the NOC (Jim and Eric) for helping us setup this 
service.

Information below is copied from

--------------
IETF Network Experiment

This is a network experiment to see how NAT64 can be used, which 
applications work and not work, etc... There is no garantee of the service.

Service Information

To try the experiment, use the wireless SSID "ietf-nat64". This is an 
IPv6-only network. The nat64 router has an IPv6 enabled interface 
(2001:df8:0:72::1) on that wireless network and sends router 
advertisements for 2001:df8:0:72::/64. There is no IPv4 forwarding.

The other interface of the router is connected to the IETF backbone with 
an IPv4 address: 130.129.48.17 and an IPv6 address 2001:df8:0:48::17/64. 
The nat64 router forwards IPv6 packets as usual. Since it implements 
DNS64 and NAT64, it also translates packets when destination is IPv4. 
Your traffic to IPv4 destinations will use 64:ff9b::/96 on the IPv6 side 
and after translation, will use 130.129.48.17 as source address.

Configuration

To use this service, your computer MUST BE CONFIGURED TO RESOLVE DNS 
names to the DNS64 DNS server. PUT "2001:df8:0:72::1" as your DNS 
server. Moreover, you might want to disable IPv4.

DNS IPv6 address: 2001:df8:0:72::1

Default IPv6 gateway: 2001:df8:0:72::1
Network: 2001:df8:0:72::/64
Translating IPv6 prefix: 64:ff9b::/96
Translated IPv4 address: 130.129.48.17

Important Notes

Please note that the nat64 router is a linux laptop running on a "slow" 
PPC processor with a single physical interface. Therefore, performance 
is not garanteed...

Please note that our tests shows that MacOSX SnowLeopard does not follow 
CNAMEs on IPv6-only networks. Therefore, you might see web pages without 
images, sites do not connect while others do. The bug has been reported 
to Apple.

The implementation is available as open-source.

If you find any issue, please send email to support@viagenie.ca
