	defaultrouter should match the gateway IP address for the virtual  
interface you're using in FreeBSD under vmware; defaultrouter is an  
alias for the default route use by the kernel for directing packets  
(this can be viewed by looking at netstat -nr and looking for the  
default route, or "route show default"--more verbose output). The  
subnet/IP should match something similar to what's provided with  
DHCP--just in static form (which /etc/rc.conf will provide).
