Captive Portal sessions after reboot

[miclan]

Everytime I made an upgrade to a new Opnsense version that needs a reboot users connected to wifi network through Captive Portal (with Radius Authentication) needs to logout from Captive Portal and login again because network connection doesn't work.

Is it a normal behaviour of Captive Portal?
What can I do to keep users connected after a reboot?
Thanks

Is this a Nano image and / or are you using the /var MFS option?

It's a full installation on HDD.

[fabian]

yes but using a tempfs as /var partition may lead to data loss on reboot. For example, the database may be deleted on reboot.

[miclan]

OK Fabian, thanks.
What can I do to change that?
Is it possible to avoid db deletion on reboot?

[miclan]

I found this settings called "Periodic Captive Portal Backup" on System-> Miscellaneous Menu
Now it's Disabled.
Could be a solution?

[fabian]

you can disable the ram disk on https://your-opnsense-host/system_advanced_misc.php

[franco]

Not sure, but the option may only back up vouchers.

The real question still is: are you using /var MFS?

[miclan]

I'm sorry Fabian, I checked my actual RAM disk configuration here https://my-opnsense-host/system_advanced_misc.php and I can confirm that /var/RAM disk and /tmp RAM disk are both UNCHECKED (so I think disabled)
Do I need to check one?

[franco]

No, your setting are ok. It may just be a loss of state in the firewall because of the reboot.

Thanks Franco, so what can I do? It's very annoying for my users. If I need to reboot they lose wifi connection, I try to give you more informations: they keep connected to our wifi network, but there's no traffic. The only solution is Logout from Captive Portal and login again.

Can you open a ticket at https://github.com/opnsense/core/issues so the author (Ad) can take a look at this?

Obviously reboots should be done when no users are around if that can be avoided, but I agree that it would be prettier if such info was kept and restored.

Maybe it even is but we are simply missing the restore, hence the ticket.


Thanks,
Franco

Thank Franco, I opened this ticket https://github.com/opnsense/core/issues/1807

Thanks, I have it assigned for assessment and will follow up here when we know more.
