If it helps, Sixxs (
https://www.sixxs.net/main/) is a very highly
recommended tunnel broker. I have not tried it and am not affiliated. I do
have ipv6 capability from my isp, so could help with testing.
There's also Hurricane Electric's free IPv6 tunnels.
BTW: one issue that I have seen with IPv6 and address privacy extensions
is that, since temporary address handling moved to user-space
(NetworkManager I guess?) instead of kernel-space, temporary addresses
are expired even when they are still in use. This affects anything that
uses long-lived sessions (such as SSH to a server) and is highly
annoying.
The RFC (4941 section 3.4) says:
"As an optional optimization, an implementation MAY remove a
deprecated temporary address that is not in use by applications or
upper layers as detailed in Section 6."
