Ipv6 down

DHCPv6 is not the thing that's pushing GWs. You need RA enabled.

of cause, i have enabled RA. it is can get DNS server, but can't get default ipv6 gateway

1/ Remove the RADVD service from service watchdog!
2/ Kindly configure your gateway monitoring so that it reflects your super-sucky connectivity which results in RTTs in 300+ms range so that it does not think one of your zillion WANs went down every couple of minutes. Or disable the monitoring altogether.

I've been having this issue for a few weeks now, as well. Only using one WAN. The radvd process seems to start on bootup, but the first boot after an upgrade it seems to not function. Restarting radvd or rebooting seems to fix.

Can you post your radvd.conf, or at least examine it to confirm that it is correct.

I obscured the prefixes and internal domains. Everything else is as generated by pfSense.

prefix 2001:470:d:1085::20/128 ??? How so?

If it only happens after an upgrade then it could be many things. My course of action when anything like this happens is to do a fresh install. Any junk left around after an update is then cleared.

The guy's lost any track of what's configured on his box. There are multiple threads here showing the mess configured there, 12 or so WANs (mostly tunnels and VPNs). The info he posted on this thread is vastly incomplete.

Guest

@doktornotor - I may be being dense, but can you have /128 prefix?

doktornotor

He enabled DHCPv6 server on something where's it not supposed to be enabled at all… I have no idea what's his opt8 interface, nor any desire to debug this mess.

I frankly doubt that nonsense has ever worked. Look at this:

I stand corrected. I tried another reboot and it stopped working again until I restarted radvd. I think it might have been a coincidence and it arbitrarily works or doesn’t work on a reboot.

Guest

Your issue is not the same as the OP.

Try a fresh install and go from there.

I only have one question after seeing that…

Why? :o
