Captive Portal HA - Sync DBs

[yut.sin1301]

Hi there, My name is Jeen

We're using opnsense on two servers using carp

Everything works as expected, but we have a network where user need to be loged using the captive portal.
The portals configuration are synced like they should, but the sessions db aren't synced at all.
It means if the master fail, users will have to relog, and any connection to any service will be lost until so.

Is it possible to sync active session between the two opnsense box ? This is a little critical for us, so any "dirty" solution will be very welcomed ! At least until a proper one exists. Thanks a lot !
