I would think that the best way to do this would be to add a static IP
to your rc.conf file. It's pretty simple edit rc.conf and change the
line which says 

ifconfig_yourinterface0="inet 192.168.1.1  netmask 255.255.255.0"

changing the address to suit your situation. It might then also help if
you alter the DHCP servers address range so that you don't accidentally
get conflicts.
