Thanks for trying the NAT64 network (SSID ietf-nat64) and reporting your experience. As far as we can tell, the issue you reported is either an issue of the NAT64 implementation’s handling of that specific traffic or the given application vendor's implementation. We’re collecting all the issues that come up and will pass the reports back to the vendor at the end of the week. Hopefully this will lead to better implementations and greater functionality for the next meeting. If you’re curious about other known issues, please see

If you have additional input on this issue please update the ticket, if you see new issues please open additional tickets.

Thanks -

FYI, TunnelBear? (which is IPv4-only, allegedly based on OpenVPN) also fails, entering an infinite loop of connection attempts.
