ipv6 routing Hurricane "Prefer IPv4 over IPv6"

[Laxarus]

Hi,
I just setup HE tunnel and now successfully ping ipv6 addresses and I can see my ipv6 when I check "what is my ip".
However, it seems this option "Prefer IPv4 over IPv6" does not appear to work for me or I misunderstood how it works. I have enabled to prefer ipv4 but it seems on the contrary whenever I ping a local host by hostname or go to website, it seems to prefer ipv6 instead of ipv4 and this creates issues.
The second issue is for some reason, my setup do not pass https://test-ipv6.com/ check for ipv6.

Anyone knows what might be the issue with these?

Prefer IPv4 over IPv6

Like https://forums.freebsd.org/threads/ipv4-ipv6-preference.15697/ but the other way around ?

pfSense, or FreeBSD, will behave according this settings, but keep in mind that pfSense doesn't initiate a lot of outgoing connections.
If some device on your LAN initiates a IPv6 connection - because the LAN 'said' IPv6 is avaible, then pfSense will not transform IPv6 to IPv4 : it can't.

Ah ... And the error was ?
https://test-ipv6.com/ should return a 10/10.

The other test, is more like russian roulette :

No IPv6, will I'm visiting the positing forum.netgate.com right now using IPv6 only...

So, let's hit F5 - and now the magic kicks in :

This is BS as it comes best : I've IPv6 DNS access, but no IPv6. And no IPv4 neither ... right, then where did this answer page come from ?

Fourth F5 :

Hummm ....

@Gertjan Yep, it is the other way around. It is possible that this is a windows issue as it seems windows by default prefer ipv6 over ipv4 when ipv6 is present.

I have also noticed that web connections seems to be a hit and miss with ipv6, (I can access google but netgate forum times out unless I disable my ipv6 on my windows machine) I think I better stick to ipv4 until my ISP provides ipv6 natively.

When testing with "https://ipv6-test.com/" there should be a message stating :
Please shut down any add filtering facilities like pi-hole, or pfBlockerng etc.
These sites are loaded (understatement) with add pages ... and most get blocked - completely messing up the "what do you support" test.
So you start hitting F5 as you know what is shown is pure BS - like : your DNS is using IPv6 and it works just fine - but you have no working IPv6 : see above, my first image.
... and you get another load of adds served == they got the money.

https://test-ipv6.com/ has none. Always works (for me).

It also depends on where you are - and where you go.

Here in France, Amazon, Google, Apple, Microsoft etc all went v6 .... but v4 is still possible if you insist

@Gertjan You are right, the ipv6 adoption here is pitiful. I just wanted to try my hand on it too see what I can do with it. But, it breaks my running system so I will stick with v4 for now.
