To get isc-dhcpd in a jail you need to give the jail access to /dev/bpf0

so you have to edit /etc/defaults/devfs.rules
add to the end the unhide rules for bpf eg.
add path bpf0 unhide

add include $devfsrules_hide_all
add include $devfsrules_unhide_basic
add include $devfsrules_unhide_login
add include $devfsrules_unhide_bpf

then in your /etc/rc.conf add

and restart the jail.

modify the configuration accordingly though =)
