WAN DHCP6 100% Packetloss

[Cannondale]

New to pfSense and currently running v2.6.
I noticed that my Dashboard is reporting 100% packetloss for my WAN DHCP6.
I have not seen this before. What do I need to do to correct this?

@cannondale

Does it work? Go to ipv6.google.com or test-ipv6.com to see what happens.

Thanks for your reply jknott. I am not able to ping ipv6.google.com.
I was able to get to test-ipv6.com. Results below:

@cannondale What does ifconfig show?

@cannondale

I assume eth1 is your WAN? If so, you got nothing, not even IPv4.

[Cannondale]

jknott, actually these results were from a workstation that has two Ethernet ports.
The workstation has internet connectivity.

@cannondale

What does ifconfig on pfSense show?

[Cannondale]

How do I capture ifconfig output from the pfSense shell?

[JKnott]

@cannondale

Can you not use ssh to connect to if from your computer? I do that all the time. If you're running Windows, you can install PuTTY.

Thanks for the ssh tip. Very helpful. ifconfig results below:

Ok, so you have no IPv6 IP address.

Does your ISP provide IPv6?

I have removed your public IP from the above output. It's usually unwise to publish that unless you can change it easily by reconnecting for example.

@cannondale

As stephenw10 mentioned, you don't have IPv6. Did you have it before? You could also mention your ISP, in case someone else here has experience with them.

[Cannondale]

Thanks for the information guys! My ISP is currently rolling out IPv6 in my area. I don't believe we have IPv6 yet. However, it's possible that there were doing some IPv6 testing.

My original post was the Dashboard is reporting 100% packetloss for my WAN DHCP6.
This was unusual because the Dashboard was reporting unknown for WAN DHCP6.
For some reason, pfSense started acting flaky last night and would only allowing access to some sites.
forum.netgate.com and email stopped working as well as other sites. I restored to a backup config and all seems well again. Dashboard is reporting unknown for WAN DHCP6 as normal.

Thanks again for all your help!

Thanks Gertjan! I have turned it off.
