Nah, very few seem to be.  Until you have IPv6-only content, it'll be hard to convince the small ISP's to make the infrastructure investment.

Let's clarify some things here.

*You* can't implement native IPv6; you have to wait for your ISP to do that.

And as far as the "Direct Tunnels", I suspect they're talking about Teredo.

Questions & Answers / Re: Cannot ping past IPv6 gateway
« on: April 30, 2018, 05:09:53 AM »
Just to make sure we're on the same page, you mean you can ping the HE side of the tunnel, right?

What happens if you disable your firewall for testing, do things work then?

Is your MTU value correct?

You must be on the insiders fast ring?  What build number?

IPv6 on Linux & BSD & Mac / Re: Tunnel very slow on ESXi
« on: April 19, 2018, 06:00:31 AM »
Update:

It's something in ESXi.  I downloaded OpenSUSE 42.3 and created a tunnel with the same results

Questions & Answers / Re: Can't tracertv6 to host
« on: April 19, 2018, 04:53:44 AM »
Well, I'd say you have a firewall in the way that's blocking traffic.

Is your tunnel up?

IPv6 on Linux & BSD & Mac / Tunnel very slow on ESXi
« on: April 17, 2018, 10:22:00 AM »
I have run an IPv6 tunnel on FreeBSD for about the last ten years, but over the past month or two, I've experienced slowness over IPv6 and have finally tied it to ESXi.  FreeBSD 11 with the latest patches running on ESXi 6.5 build 7388607. I have tried multiple ESXi hosts and had the same result with all of them. 

I've tried both the Intel NIC and the VMX NIC with the same issues.

If I run from a desktop running the same version of FreeBSD with the same patches, I get the speed I expect. 

From ESXi

Questions & Answers / Re: ICMPv6 from my network to far hosts
« on: April 17, 2018, 04:58:01 AM »
I sort of figured, but had to ask.

Are you filtering anything outbound, or does it only apply to inbound traffic? Either way, I'd turn it off and try ICMP with it off, at least then you'll be able to rule something out.

Probably yours.

Are you running a firewall?

You can open a ticket with ipv6@he.net

Thanks for reminding me of this.  The problem ended up being in the VM I was using, somewhere.  I spun up a new VM with the same OS and got 200kb/s, but when I went to a dedicated desktop, I was able to max out my connection.  Something is wrong in the VM or ESXi, but I haven't had time to delve into it more

I've not used either...can you do an export and import?

IPv6 Basics & Questions & General Chatter / Anyone else slow lately?
« on: April 04, 2018, 08:00:58 AM »
We've been having abominable IPv6 speeds over the last month or so; the max we've seen is close to 60kb/s on our 100mb/s circuit.  At the same time, IPv4 speeds are maxing out the circuit.  We're running a tunnel from the Chicago location.

EDIT:

I can confirm it's IPv6 by disabling IPv6 on my machine and running the same download.

If I try over IPv6 from my IPv6 router:

Questions & Answers / Re: Cannot view IPv6 websites.
« on: February 27, 2018, 05:49:32 PM »
My first thought was an MTU issue, but I'm not completely convinced of that yet.

What happens if you try from another machine so we can rule out the software aspect of it?
