Two Mac Addresses, one hostname, one IP address?
-
In pfSense 2.1.5-RELEASE (amd64) I can't set the same IP address to two mac addresses.
In previous versions it was as reply #2 in topic https://forum.pfsense.org/index.php?topic=53418.msg285491#msg285491 shows.
In my configuration, it is usual to set the same IP to a laptop with wifi or ethernet.

IMHO they have finally fixed a broken setup then. You should not have reservations for same hostname, mac or IP on in your dhcp server. MAC to IP should be a unique combination when setting reservations - your run into a possible problem of duplicate.
To be honest your wireless network shouldn't even be on the same segment as wired devices for security reasons ;)
If you want make your wired interface 192.168.1.42, and 192.168.2.42 on wireless for example. You could use the same fqdn if you wanted too.
Here is the thing with wireless clients - they fairly often never actually release the lease and just disappear off the network - how does the dhcp server know if he should give that IP to wired mac that asks for it when he doesn't know for sure if wireless gave gave it up, etc.
