Tunnels are ipv4 only now?
#2 see #1 #3 use happy eyeballs, http://tools.ietf.org/html/rfc6555, Chrome has a good implementation, but this does not solve MTU issues.
Because the initial connections are made just fine.PMTUD with probing should work, but does not seem to. Probably a (lack of) deployment issue.
#4 MSS hacks work at the TCP layer and still work regardless of IPv4 or IPv6.
But the equipment needs to support it. Again IPv6 lags.
#5 According to the IETF, MSS hacks do not exist and neither do MTU issues http://www.ietf.org/mail-archive/web/v6ops/current/msg12933.html
Thanks for that. I expect soon tunnels wont either.
PSA time: Please use http://test-ipv6.com/ and pass this good advice around to the people you know.
Excellent site/tool.
Thanks, Cameron
Thank you. Joe
