I agree about manpage and I star to do the same as you did - experimenting.That depends on what information You look for.
The manpage fully describes all the implemented functions, but does so in a very terse way; it is suited for look-up, not for learning.
Then, one could go the way of trial&error: all the activity can be logged, so one can just start off and experiment and observe what is happening (that's the way I went).
Hi!
I start learning firewall as firewall and IPFW firewall which I am using now. Are there more information about IPFW like is for pf firewall, please?
I search a lot but not so success.
Thank you.
I would suggest just getting a good book about TCP/IP in general. If you understand TCP/IP you will automatically understand what a firewall does and how you can use it. You will be armed with more generic information, knowledge you can apply to all sorts of firewalls and networking equipment, not just to IPFW.I start learning firewall as firewall and IPFW firewall which I am using now.
