DHCP Static assignment problem

I experienced a problem with assigning a static IP address for 2 ports on an Intel based server board.

the Mac addresses are:

XX:XX:XX:XX:XX:CC  and  XX:XX:XX:XX:XX:CD

the problem is that PFSense doe snot seem to like 2 Mac addresses that are separated by 1 digit.

I get the error:
The following input errors were detected:

This fully qualified hostname (Hostname + Domainname), IP, MAC address or Client identifier already exists.

However, if I change everything, IP, Client ID, hostname+domain and leave the MAC, I still get the error.
IF I move it from D to F or a number, it seems to accept this.

I can't change the MAC on the system in question, so I was hoping that maybe someone else has seen this and/or there is a fix for this in PFSense ?

thanks !

Just wondering if anyone has seen or knows of a fix ?

The box I am using has an Intel MB with dual NICs and believe it or not, the MAC addresses are 1 digit apart.

I want to be able to use both NICs via DHCP and for some reason it does not seem to work via PFSENSE DHCP.

thanks

Can you locally assign a MAC on one of those interfaces?

Would this happen if DHCP has already assigned IP's to these MAC addresses? Check Status > DHCP Leases. If so try deleting the entries automatically created by DHCP with the same MAC addresses.

Make sure you are assigning static IP's outside of the DHCP IP range.
