OPNsense loosing WAN IP several times daily

[Grossartig]

I recently migrated to new (temporary) hardware for OPNsense. My trusty Protectli FW4A died and, while I wait for a proper replacement to arrive, I set up an older Zotac CI327NANO as a temporary replacement and imported a backup of the configuration into it.

Currently on OPNsense 22.1.6-amd64 (as was the previous box) and having issues I had never seen before from the start.

Several times throughout the day OPNsense looses the WAN IP. I cannot see anything in the logs in that regard (or I don't know which logs to look into -- please advise), but when I issue a "configctl interface reconfigure wan", I see the following in the system log, yet the WAN IP on the OPNsense dashboard still remains blank and I have no connectivity (note: IP addresses removed from log, as I don't want to put the firewall to the test )

I even tried to reconfigure twice, without any difference. This may be related to https://forum.opnsense.org/index.php?topic=26652.0. In my case, OPNsense is directly connected (via an Ethernet cable) to my Verizon FiOS ONT (in North America). I read elsewhere that putting a network switch between the OPNsense box and the ONT may help in such cases, but I haven't tried that yet and it seems rather crude.

At the moment, the only fix is to reboot the router when this happens.

I should note that I also have IPS enabled on the WAN interface. Although this was the same with my previous OPNsense box, and did not result in an issue in the past.

If I can provide any additional information regarding my issue, or if there is anything else I should try out, I am happy to roll up my sleeves. OPNsense has been good to me for many years now, and I want to be good to it in return

Same config but different hardware so interactions between hardware, drivers and config might be at play.
I would disable IPS to begin with and see if that makes it more stable, especially with re interfaces.

We saw a somewhat similar issue and when we disabled System \ Settings \ General \ Allow default gateway switching, it stopped. Might be worth a shot if you only have one WAN connection.

Thank you for that -- yes, I was also contemplated turning off IPS. It's unclear to me anyway whether it should be configured on WAN or LAN (and have seen other people hotly debate that topic). But let's assume I turn it off and the problem goes away -- what then to enable it again?

Thank you -- I just checked and it's already disabled on my end.

Take a look at this thread... https://forum.opnsense.org/index.php?topic=27299.60

[Grossartig]

Yeah, I read through it and it may be related. I also realize that disabling the Intrusion Detection service altogether seems to allow the OPNsense box to obtain a WAN IP address. As was suggested further above (thanks!).

Disabling IPS completely indeed mitigated my WAN disconnect issue completely. Not really a good long term solution, as I'd like to turn IPS on again, but you were right, it's clearly related. Where to go from here?
