I realize that HE cannot control the MTU used by its peers, but I'm wondering whether HE plans to enable "jumbo frames" on its internal network....  Being that most network lines are 10Gb fiber (or higher speed), there seems to be no reason not to enable some sort of jumbo packets with an MTU greater than the 1,500 byte 10/100 Ethernet standard.

How about it HE?

My colocation provider has enabled 9k (9,216 byte) frames internally, but clamps the MTU to 1,500 at its external routers (as its peers don't implement jumbo frames).  However, HE is one of its peers... so...?  ;-)

The long answer is, if your carrier NAT is a one to one, and they forward all traffic to it to your private IP, then yes, it will work.

The issues are as follows:
  • Your IP needs to be pingable, even if through NAT
  • There is a option to get ddclient to work with dynamic tunnels with changing IPs
  • The NAT needs to be complete forward as proto 41 is not a port and will not work with just port forwarding.

Interesting enough, as of June, that will be the second of three major tunnelbrokers that have gone down.  If you know how to get the public IP to foward all traffic, then you can easily work out the issues.  Otherwise, it might be just easier to look at Carl's answer above and ask your ISP for IPv6.

because my ISP installed a router box, my router box has RFC1918 IPv4 addresses on both interfaces

The tunnelling protocol used with HE is 6in4, also called protocol 41. 6in4 packets will contain an outer IPv4 header and an inner IPv6 header but no UDP or TCP header.

Your only hope to use 6in4 and HE with the ISP installed a router box is that it has a DMZ feature as described below that you can use.

When an endpoint of a 6in4 tunnel is behind a NAT, one can in some cases still make use of the DMZ feature of a NAT router. The NAT router will then forward all incoming proto-41 packets to the configured host, thus making the tunnel work. Some NAT devices even allow transparent operation of 6in4.

I have a dynamic ip on carrier nat; my ip is not pingable.
I have a tunnel through sixxs, but they are closing down.
Can HE work like that?

A few months have passed, many places are relying/verifying DANE entries, and is its still out of scope for the HE DNS servers?

Sorry to "resurrect" a topic - making a new one for this year old question would have the a lesser effect. After all, this one has, uh, history.

Down again, though endpoint still pingable. I guess just maintenance?

Edit: Never mind. Working again fine. Just a minor hickup. Status page shows all green again as well.

March cumulative update.

FWIW not all of microsoft ipv6 issues were fixed.

CU? You mean Creator's Update? So that means you're on the Windows Insider program? So it's not fixed on the stable/mainstream channel?
