Thank you both very much for the given hints, I will look into them! Sorry for the double post (I first used the wrong mail address).

Re: [pfSense] Documentation about Firewall Lookup Process, State Table, Firewall Rules Table
Pfsense is based on openbsds PF (PacketFilter) and runs freebsd as base OS. That should give you enough to google how it works. Also remeber that this is opensource and everything is freely available. The source code tells you everything there is to know ;-) Good luck :-) ons. 3. juni 2015, 14:33 skrev Lukas Hubschmid (s) < lukas.hubsch...@students.fhnw.ch>: > 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! > > KR, > Lukas > ___ > pfSense mailing list > https://lists.pfsense.org/mailman/listinfo/list > Support the project with Gold! https://pfsense.org/gold > ___ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
