I am having issues trying to reset the IP address of the (onboard) NIC 
under FBSD 9.3-p2:


[root at kabini1, /etc, 9:07:22am] 506 % ifconfig  re0

I used ifconfig to reset the netmask yesterday successfully, just can't 
get the address to change. I need to (temporarily) change the address to 
setup a newly acquired WatchGuard FireBox Edge firewall appliance, which 
apparently requires the addressing computer to be on the same (rather 
restricted) subnet. Any help appreciated :-) .... TIA ....
