Re: bpf filter to filter on *starting* port?

maybe adding "config ignore_ports: tcp 9000" to your conf file might
work. I'm not sure if this acts the same as a bpf or not.

I think that would work. it will discard packets to/from 1.2.3.4 with
either a src or dst port of 9000.



Sorry - I said "any host" - doing single hosts is doable (as you say) -
it's the general rule that's beyond me
