Unable to pass IPv6 Tests
-
So out of the box lan has ipv4 enabled - but I am not sure there are any rules that allow ipv6 out.. What are you lan rules in pfsense? Seems you can ping out, so you must have that allowed..

So that was a very good suggestion. Right now the rules I have is the following:
Floating:
IPv4+6 ICMP – Any <-> Any * *
IPv4+6 TCP/UDP -- !Guest_Network (Open WLAN) -> !Private_Networks * *Private_Networks is simply a list of private class A address spaces. These should allow access out.
On that specific LAN interface, I have one additional IPv4 rule that allows full access to the router.

You need to have a few things.
1st I recommend having DNS running that works with IPV6 also. What are you using for DNS?
Second, and this could be very important, what browser are you using?
-
I've run the tests in Chrome and IE.
As for DNS, please see attached.
-
Switch your IPV6 DNS to "none" and see what happens.
Chrome for sure should work out of the box with IPV6.also try these as your IPV6 DNS - just to test.

2001:4860:4860::8844I don't use those, but I know they work.
-
Should I also remove the DNS entry or just change the gateway to none?
The thing is, IPv6 lookups work in the current setup (eg. I can ping ipv6.google.com and receive a reply).
-
Try just setting gateway to none and try using the two IPV6 DNS I provided.
-
why do you have your rules in floating and not on the actual interface - out of curiosity?
-
The pfSense UI will not allow me to enter those DNS servers without configuring gateway interfaces.
As for the floating rules, there's a few other VLANs which they apply to, I'm just not concerned with IPv6 on those VLANs.
-
Thats strange to me…
I have 5 interfaces and, up till recently "none" was selected for all my dns server interfaces. IPV4 and IPV6.
Anyway - obviously whatever box you are on is getting IPV6 obviously. I assume you are not testing connectivity from pfsense, but rather are using the same machine you are attempting to browse the internet from?
-
Correction, I was able to implement these without specifying the gateway interface and I got the same result.

2001:4860:4860::8844I also disabled the firewall on my workstation for good measure. Still fails the IPv6 tests.
-
But your WORKSTATION is able to ping, for example, those two IPV6 addresses I gave you?
-
Yes, that is correct.

I've resolved this issue. The firewall rule IPv4+6 was not applying correctly. Listing an explicit IPv6 Any -> Any rule fixed the problem. I'll work to explore these rules in more detail.
-
Strange - Just to look into chrome, past this in your chrome browser:
chrome://net-internals/#dns
Then click "clear host cache"
Probably will make zero difference, but why not…
If that doesn't work, take a look to see if there is some strange rule in your firewall (or lack of a pass rule) that is letting ICMP pass but not allowing HTTP/HTTPS.
-
Ahh - so not passing IPV6 correctly (-;
Works now?
-
And again why do you have them in floating in the first place? Are they set to quick, rules in floating are for SPECIAL rules..
For example
" I'm just not concerned with IPv6 on those VLANs."But you had a rule that should allow ipv6 out, which would be applied to ALL interfaces.. I don't recommend putting anything in floating unless it really needs to go there.
