I bumped into this (rather old) feature request from Wesley K. Joyce:

"I would like to suggest making the DHCP - Static ARP feature more flexible. I
am suggesting making that feature have 3 radio buttons.
1. Static ARP OFF
2. Static ARP for DHCP Reservations only
3. Static ARP for DHCP Reservations and no other clients are able to
communicate with router

Option 3 is the behavior experienced now."

See http://www.mail-archive.com/support@pfsense.com/msg04458.html

Just wondering if this request was taken into consideration.

Option 2 would prohibit users from manually claiming IP addresses that were already reserved in the DHCP server for specific hosts, but it would still allow "unknown" clients to get a DHCP lease.

This way you know that the IPs you reserved in the DHCP server really belong to the machines you intended them for (unless their MAC addresses were cloned), without banning "unknown" clients.

In 1.2.3-release there is only the choice between 1 and 3.
