I= m trying to implement the FreeBSD equivalent or similar way of doing things l= ike I did on my Linux Router. Are there are equivalent ways/programs for the= following: 1. Reverse Path Filter (Like on Linux). 2. Protection against DHCP Starvation attacks. 3. DHCP Snooping 4. Reply-Only ARP system with features like(automatically adding arps for le= ases) that keep people from setting a static ip on the network and bypassing= the queueing done by pf. P.S.: If there are any ways of doing these options above can you point me to= the right documentation as I have tried to research but couldn=E2=80=99t fi= nd any thing on these subjects listed above. Thank you, Lou=
