22.7 Legacy Series / Firewall Frequently Locking Up, Requiring Hard Reboot

« on: August 14, 2022, 01:45:45 am »

Every so often, up to multiple times per day, my firewall appliance locks up and requires a hard reboot to restore services and internet connectivity.

So far, I have been unable to find any logs or crash dumps that would help me isolate the issue outside of one time, which I did submit via the web interface.

I have no idea where to start. Can someone point me in the right direction to troubleshoot this issue? At this point I'm not sure if it's hardware or software.

I'm running it on a KingNovy fanless PC with 6x Intel I225-V, a Celeron N5105, 16 GB of RAM, and a 256 GB NVMe drive.

18.7 Legacy Series / DHCPv6 Leases No Hostnames

« on: January 29, 2019, 05:48:52 pm »

Under DHCPv6, even with the option checked to add DHCP leases to DNS, it does not show host entries under DHCPv6 > Leases, and when my DNS server queries OPNsense for my domain, no IPv6 addresses are returned.

Running version 18.7.10_3.  Just set it up last night, so I am not sure if the issue occurred on previous versions.

18.7 Legacy Series / 18.7 abuse.ch/urlhaus rules still cause Suricata crash

« on: August 02, 2018, 01:49:15 am »

Enabling this rule set still causes RAM usage to grow until Suricata crashes... there is nothing in the Suricata log and the only entry in the general log is "kernel: pid (suricata), uid 0: exited on signal 6 (core dumped)."

Disabling the rule set remains the only way to keep Suricata from crashing.  I've tried reporting the issue to abuse.ch as well but haven't really gotten any response except "fixed," which it isn't...

Please let me know if there's anything I can provide to help narrow down the cause of the issue.

18.1 Legacy Series / 18.1.12 Prefix Delegation Bug?

« on: 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?
