Running into a similar issue. Netflow crashes after a minute or two. Not sure, but the problem occurs after adding an additional interface via "Interfaces: Assignments" for ovpns1. Maybe there is a 'corpse' in a config file now?!

Output:

I tried to reset and repair via GUI and also a rm of the sqlite files. But nothing helped.

Thanks you for your answer. Would it be possible without authentication? At least to log https traffic instead of just let it pass the firewall with permit tcp 443.

Hello,
after reading some docs I am not sure if this will work: I want to setup a transparent proxy with authentication. As normal http sites are no big deal, these sites should be cached. I think this is the easy part. For all (!) https sites, I just want a basic authentication with local users (to avoid MITM and proxy cert). Is this a common setup and will this work with OPNSense? Any hints for the implementation?
