I see you have gotten no replies. This maybe to the lack of any details 
provided by you. You will get better results if you provide details 
about what your trying to do, what hardware you are using and what 
version of FreeBSD you are running. BY default bpf is disabled for 
jails. Have no idea what pof is.
