Hello,
I have a crazy question about pf: with iptables on linux you have a module called u32 which let you inspect a specific part in the packet at the packet level and act on that, I am searching for an alternative with freebsd/pf for some time now but did not found anything yet.
I read more than one time around that pf can rely on external application to identify packets but did not found anything more than the mention of it about that, maybe i just misunderstood what i read but if not it may be a solution.
The reason I need this is to identify dhcp requests from specific equipments and redirect them elsewhere while all the other requests will just pass and be handled by the dhcp daemon running on the box.
