Well, I had to reboot mine for an unrelated issue and it started handing out IPv6 addresses again and the conf files look normal.  Not really sure what happened there as I already tried rebooting it twice before but... It's working for now.  I'll try to grab the files if it stops working again, though.

Yeah, it's super odd since from what I can tell, everything should be working according to the logs.

I'm on 18.1.13 now, and I suppose if your test unit is working fine something might have gone wacky during the update process to 18.1.12.  I'm running it on a Dell PE R210 II with the built-in dual Broadcom gigabit NIC (forget the exact model... 5720 maybe?), an E3-1220v2, 8GB of DDR3, and a 128GB SATA SSD.  If you need more detailed specs I can grab those tonight when I have access to the machine again.

I can also post the contents of the files you requested later on as well.  Backing up the config and re-installing might be a good idea, though.  If all else fails I'll give that a try.

How much RAM do you have?

8GB.  RAM usage doesn't grow to 100%, though.  Last I saw it grew to about 2.5GB before Suricata crashed.

Well, it wasn't fixed... Re-enabling the abuse.ch\urlhaus rules on 18.1.12 resulted in Suricata crashing again until I disabled the rule set.

After updating to 18.1.13 I am now experiencing the same issue with memory usage growing until Suricata crashes, then going back to normal.  This only seems to occur if the abuse.ch\urlhaus rule set is enabled.  Disabling it again seems to have stopped the issue for now.

Here are the logs.  Note IPv6 is now not working as soon as I changed it back to a track interface, and the dashboard no longer shows an IPv6 address on the LAN interface, either.

Some people reported that their ISPs refused to give a new lease unless you changed your DUID. You can do so under Interfaces: Settings.

We are highly confident that IPv6 does not suddenly stop working due to a 18.1.x release.

My ISP is giving me a lease.  The issue is that the OPNsense box stopped handing out IPv6 addresses to LAN clients.

I suspect Franco is correct, but just in case, if that does not solve it.

Set the system back to track interface on LAN.  On WAN set IPv6 to dhcp6 and enable dhcp6c debug.

Goto Services->DHCPv4->Log File. Filter entries regarding dhcp6c and post them so we can see what's going on.

I will post the entries as soon as I'm able to collect them.  Thanks.

18.1 Legacy Series / 18.1.12 Prefix Delegation Bug?
July 24, 2018, 05:06:34 PM
After upgrading to 18.1.12 I noticed my LAN was no longer receiving IPv6 addresses.  I did not change my setup.

WAN interface is set to DHCPv6, LAN interface is set to Tracking WAN interface with prefix ID 0.  The LAN interface does receive an IPv6 address but does not hand out IPv6 to the LAN clients.

If I configure the LAN as Static IPv6 using the same /64 prefix it gets assigned as a track interface and then enable DHCPv6 and RAs, it works fine.

The former setup with LAN set to track WAN was working normally up until I upgraded, any ideas why it stopped?  What information can I provide to help track down the issue?

18.1 Legacy Series / Re: 18.1.12 suricata crash
July 24, 2018, 05:02:56 PM
For me this was definitely due to the abuse.ch\urlhaus rule set.  Once I disabled that and re-downloaded/reloaded the rules, Suricata stopped crashing.

It seems they have an issue with this rule set currently.
