[SOLVED] Gateway down (dpinger) but DHCP works

[seki]

So last night I've done something that I was thinking about it long before I've dug into dpinger and other activities helping me understand how's the connection between my OPNsense and ISP modem working.

So until last night my OPNsense instance was more than a year old. I mean it was updated all the time whenever new (full, not dev) version was released. But I installed it having version 21. Today we have 23.

And you know what? Everything simply went away!

Someone might say that I've probably messed up with the config but ummm - no, I don't think so. Before the clean install I've downloaded full config and took literally all screens from the GUI.

Once fresh install was done I did reproduce all setting based on the screenshots I've had from previous OPNsense install. 12 hours and no problem at all. So then I've backed up the manually (screen & click) recreated settings, restored the backup settings from the old install and when another 12 hours of testing were ongoing I've compared the XML (config) files in the mean time searching for any differences I could probably have doing the screen&click configuration. Basically no difference if you ask me.

And guess what? Another 12h test and nothing.

It's great that it worked out for you in the end.

This was actually one of the last things I would personally recommend: a clean install.

I have a similar OPNsense year and a half old that I upgraded to the current release, and I have a bit of trouble with static routes not being installed into the Route table after a reboot. Personally, I plan to do a clean install, as I think something could go bonkers during the upgrade procedure.

Upgrades can cause weird behavior sometimes. This also applies to enterprise devices like CISCO and Juniper (I've seen a lot of such).


Keep an eye on this; I'm assuming that once it's stable for you over some period of time, you can flag this thread as solved. It may come in handy for somebody else who will hit a similar issue.
