Ticket #548. Change message displayed when modifying an interface to actually tell people to modify dhcp server setting after applying settings since the interface configuration/ip will only change after applying settings and pfSense does not read the interface address from the config but from the interface itself and the complications for this and possibly other cases are not worth the effort.
