Default Deny Rule IPv6

[dscott_casd]

I'm trying to get IPv6 to work, everything is configured and the router can ping and traceroute to IPv6 addresses, but clients trying to actually use the router are getting timed out at the firewall.  I've tried flipping the "Allow IPv6" checkbox in the system settings, gone over my configs probably 20 times by now, and still cannot get this to work.  Please could someone give me a hand here?

I've tried to include screenshots, but the attachment limit is being difficult.

Did you apply the pending firewall rule changes?
Could you post the output of the command "pfctl -sr" if you have console/SSH access, please. If not easily possible, please post a screenshot of the floating rules.
I can see that you have two WAN interfaces. Does the firewall have the right interface as default gateway?

[dscott_casd]

Yes, the firewall has the correct interface as the default gateway, and yes I've applied the pending changes.  Here is the output of pfctl -sr:

That's really weird... I assume vr0 is your LAN interface? Then the rule

Code: [Select]

pass in quick on vr0 inet6 all flags S/SA keep state label "USER_RULE: Default allow LAN to any rule"Should match and allow the traffic...

Are you positive that the shown log in the screenshot is actually the reason for the connection timing out? Maybe it was a previous error (date/time?) and the current problem lies somewhere else?

[dscott_casd]

I did a little more testing and find that my clients can ping both the LAN and the WAN interfaces, so traffic is obviously making it through the firewall.  Seeing that the firewall can ping and traceroute to IPv6 servers, but clients can not, I'm not sure where else to look at this point.  The gateways are set up correctly (to my knowledge), so I'm at a loss.  This is a test server, so I am willing to let someone have access in to have a look around for anything that I could have missed.

Everything looks normal and should work out of the box. If the offer still stands, I'll gladly take a look via SSH. Please PM me for details.
