IPv6 cannot connect to Internet

Shouldn't it work this way
Yes. So you might (also) have different problems.

I'm just asking to understand the process: Shouldn't it work this way if it's the thing you guys told about?
My prefix hasn't changed in almost 7 years, so I don't have much experience to work from. However, I would expect the pfSense LAN interface to show the new prefix and the router advertisements should tell other devices on the LAN what the new prefix is.
-
I don't know, I still don't think it's a prefix problem because I used it as it is for a long time without a single problem and now I simply can't connect to the internet with it.
But I can't see any problem on my settings and my ISP says there's nothing wrong on their side either. I'll just turn my IPv6 network completely off until I figured it out because it really causes my network go crazy.
Do you have any recommendations to check or solve?
-
@crazypotato142 Check the IPv6-addresses closely, are they really using the same prefix or do they differ. It must be the same prefix as pfSense LAN has.
In Windows use ipconfig /release6 and then ipconfig /renew6 and watch out for problems.

@Bob.Dig They are like this right now:

Note: I can't ping an IPv6 address over pFsense interface either.
-
@crazypotato142 The first address already looks wrong. At least the prefix is the same.
-
@Bob.Dig
pFsense itself can't connect to anything over IPv6 either. I can't use IPv6 ping, not even get into the Update page cuz Netgate has IPv6 addresses for their website. -

That screams for a big problem, might be your ISP at this point.
-
I'll test it with their default router and keep here updated. Thank everyone for the help.

Thats what i have been thinking through out this post.

I saw in your settings that you request a prefix only, not a WAN address. You might have to specify your LAN interface as the source address. You use the -s option for that.

How do I do that?
Also I didn't do such a thing after we got my IPv6 in this thread

about 2 hours agoI don't know, I still don't think it's a prefix problem because I used it as it is for a long time
In an earlier post I suggested you capture the DHCP6 sequence to see what prefix you're assigned, to see if it's what's actually being used. Have you tried that?
In the capture you'll see 4 packets:
Then, in the last packet, should be something like this:
Compare the prefix with the one your network is using.

@JKnott
Package Capture stops when I plug the WAN cable. I'm doing it according to this: https://forum.netgate.com/topic/172514/capture-full-dhcp-or-dhcpv6-sequenceUpdate:
It doesn't work with the default router my ISP gave either. Prefix and IPs everything seems fine but nope, it still doesn't connect. I also checked Windows ipconfig while on it and it just showed single IP for each, prefix matched as well. -

I just tried and it works fine here.
Do you have a switch that you can use to make a "data tap"?
-
@JKnott I'll try it again later today.
Unfortunately no, I don't have a managed switch.
