No IPv6 connectivity after upgrading to 2.5.0 RC
-
I see 'dynamic' under Gateway as well, but 'Monitor' is blank, and RTT, RTTsd, Loss and Status are all 'Pending'.
-
@andrew_241 Try restarting the dpinger service. That should get rid of the "pending".

Just thought I would mention this: my pfSense box is able to ping IPv6 addresses with a source address of either 'WAN' or 'LAN'. When 'Localhost' is selected, I get 100 percent packet loss:
PING6(56=40+8+8 bytes) ::1 --> 2607:f8b0:4000:800::2004 ping6: wrote www.google.com 16 chars, ret=-1 ping6: wrote www.google.com 16 chars, ret=-1 ping6: wrote www.google.com 16 chars, ret=-1 --- www.google.com ping6 statistics --- 3 packets transmitted, 0 packets received, 100.0% packet loss

That's fine. Would be a fail if otherwise, as localhost, the 127.0.0.1 and ::1, isn't routaable.

I did a clean install of 2.5.0-RELEASE, and on the unconfigured system, I was able to successfully test IPv6 connectivity on a LAN-connected device, but the gateway still shows as 'Unknown'. It's still working after restoring my configuration, though I did not restore the CODEL limiters I had.
-
@andrew_241 I'm in the same boat. I got IPv6 connectivity back up as well, but had to disable my CoDel limiter, since the gateway isn't receiving an IP address.
-
@k3nb5t It looks like my IPv6 connectivity is down again. I didn't reenable the limiters or anything, just restarted the gateway device in front of my pfSense box.
-
I didn't mention this last night, but I did enter my gateway device's link-local address (that 2.4.5-p1 used) under 'Monitor IP' in System/Routing/Gateways/Edit. Some people reported that that got IPv6 working again, but in my case, it doesn't seem to solve the problem.
-
I disabled a couple floating firewall rules, and IPv6 started working again:
Both rules specified passing traffic in the 'out' direction. I think I was messing around with something a while ago.
-
@andrew_241 Yeah, those look like "policy routing" rules since you were specifying a gateway (rather than letting pfSense use the default gateway). But if you only have one WAN connection, or you don't want to route specific traffic in a specific way, you don't really need those rules, because everything can just route through the default gateway.
But since you had those rules... there is a deeper issue with the IPv6 gateway behind the scenes, so the IPv6 rule was not functional because of the bug, and was preventing your IPv6 traffic from flowing as a result.
