Re: [Openvpn-users] Problems setting up dual-stack OpenVPN server on a Windows 10 host

[Daryl M. <dar...@te...>]

Hello,

 

That post looks familiar because it's my post. I didn't find any solution to
my problem so I'm trying here.

 

Since it's not clear to you what I'm trying to do, it's probably not clear
to others so I'll try to explain again.

 

I have two dual stack networks. One uses a hurricane electric tunnel for
ipv6. The other uses native ipv6. When I run ipv6-test.com or test-ipv6.com
on either network, they both verify that ipv6 is working properly using
chrome, edge and ie11. (I don't use firefox, but it should not be different
than the other browsers.) When dual-stack is available, all browsers are
supposed to default to ipv6 and only fallback to ipv4 if ipv6 has excessive
latency. Both of these tests verify that all three browsers are defaulting
to ipv6 and falling back reliably.

 

Here is what the ipv6-test.com browser test looks like when it passes:

 



 

When I use openvpn (not my server, but a service), it fails the above test
and reports it as an error. The reason I'm setting up my own server is to
conclusively determine if this an openvpn issue. If it is, I'll report it as
a bug. I'm not familiar with the code, but based on the symptom, I would not
be surprised if ipv6 packets are inadvertently getting buffered.

 

You are the only person I've heard from who has a working windows 10 dual
stack server! I'm glad to hear it's possible. I would really appreciate if
you would explain how you have the server configured (not only the
server.conf, but also the networking and routing), because as I explained, I
haven't been able to get my server working. Alternatively, please try going
to ipv6-test.com and test-ipv6.com and reporting your results.

 

I hope that clarifies sufficiently.

 

Thanks again.

I noticed this on the Forum:

Looks very familiar ..

 

 

 

I don't get what exactly you are trying to do but I do use W10 as OpenVPN
server with dual stack and that works.

 

As for  "browser failover" from IPv6 to IPv4 ?

Firefox does not appear to be able to use IPv6 addresses directly.

(Unless there is a hidden setting I don't know about)

 

But W10 + OpenVPN Dual stack server work as expected.
