Looks like his other post was stuck in the moderation queue and
approved, I'd have killed it but I didn't notice he'd already managed to
get it through to the list.
Hello everybody,
Is there any documentation about:
* the process how pfSense firewall handles packets (lookup in firewall
rules, lookup in state table, add new state, ...) e.g. a flow chart
* how the firewall rules are beeing (data structure)
* how the connection states are beeing (data structure)
Any hints are greatly appreciated!
While not that low level (which as others have stated could be found in
PF docs from FreeBSD and/or OpenBSD, plus the source), this should also
be of interest:
https://doc.pfsense.org/index.php/Firewall_Rule_Processing_Order
