Edgar, Sounds like you need to build an adaptive firewall. I would suggest to start with The Book of PF by Peter Hansteen. An excellent resource. That might be a good starting point for you as well. It has some good portion of the information on adaptive firewalls.
P.S. Thank you, Peter for such a great book. -bogdan > On Oct 10, 2018, at 8:17 AM, Edgar Pettijohn <ed...@pettijohn-web.com> wrote: > > > On Oct 10, 2018 7:58 AM, "Peter N. M.
