in the logging settings you can set if the default block rules should log etc. You may have not configured or misconfigured it. The log looks like a lot of data joined by a comma (",").

to read it, you may use a library - for example, I wrote this one for logstash: https://rubygems.org/gems/logstash-filter-opnsensefilter
You can find the source code for this library here: https://github.com/fabianfrz/logstash-filter-opnsensefilter/blob/master/lib/logstash/filters/opnsensefilter.rb

Here is the OPNsense internal function:

Also, das Thema ist bridge mode. Ich möchte den AP eigentlich nur gerne wie bei jedem Schnullepulle 08/15 Router benutzen. Ist es dann egal, ob WLAN und LAN den gleichen IP Adressraum oder einen sich im vorletzten IP Segment unterscheidenden Adressbereich benutzen? Denn die bridge verbindet ja dann beide Bereiche auf den entsprechenden Layer.

In dem Fall gibt es nur mehr die Bridge und die beiden Schnittstellen brauchst du nicht weiter beachten. Du musst dir nur einen DHCP range auf die Bridge konfigurieren und dann tut es genau das, was ein handelsüblicher Router für den Heimgebrauch macht. Unter Umständen musst du hier die Firewall kurz abschalten, damit du dich nicht selbst raus wirfst (habe ich noch nie gemacht - kann es daher selbst nicht sagen).

Wenn du das gleiche IP-Netz verwenden willst, musst du dein Lan und dein WLAN auf eine gemeinsame Bridge legen, sonst geht das nicht (die Firewall glaubt sonst, dass es sich um das gleiche Netz handelt und nimmit die bessere Route (in der Regel das verkabelte Netz). Als Alternative kannst du natürlich auch einfach ein anderes Netz verwenden (vorletztes Byte des IP-Bereichs um 1 erhöhen).
In dem Fall kanst du 192.168.1.1 als LAN IP verwenden und 192.168.2.1 als WLAN IP. Der DHCP-Bereich muss dann auch entsprechend angepasst werden. Der Vorteil hierbei ist, dass du das WLAN als weniger vertrauenswürdig einstufen kannst und damit viel restriktivere Firewallregeln verwenden kannst.

And the "main firewall" needs to know the VPN networks for the route back.
I would say that the OPNsense VM knows all required routes as it has only two: The VPN network and the default gateway.

Most stuff is written in PHP (its the main scripting language) and booting any system is something where it should be busy.

configuration should not happen too often but it should be possible to configure the system to avoid logging to disk. In this case you can send all your logs to an external logging server using syslog. If this is a logstash server, your log messages can be indexed for search, stored on a storage server and sent to a SIEM engine.

Enterprise SSDs are usually SLC instead of MLC which makes them last longer and be faster but it will increase the price a lot. If you want to to be prepared for disk failure it would be cheaper to mirror the data using RAID and do regular backups of important data.

Just if anyone likes to test:

Log in via SSH, and run this in the shell:

pkg install os-tor-devel

Docs may be available soon (URL will probably be https://docs.opnsense.org/manual/how-tos/tor.html)

The CA has the advantage that you can use it in the proxy too ;)

An 8GB CF card is enough for the operating system and the plugins but you cannot run a developer environment on it and you cannot use features like caching (for example the file system storage of the proxy).

If those 100 PCs are windows computers and belong to an AD domain, you can use a group policy. On most other operating systems, it should be possible to roll out the certificate using SSH.

from the rule I would say that there is something wrong with the gateway set as an empty set is given in the rule.

the DHCP server may know it as it is a field that is sent with the DHCP request.
