That seemed to have done the trick, manually. Im guessing, I could put the 
same thing in my rc.conf file, but with proper syntax:

ifconfig_fxp0_alias0="inet 192.168.2.222 netmask 0xffffff

On a side note, if you set something up in rc.conf, how can you manually 
start it without having to reboot?

Thanks,
