The above configuration will do just fine, but if you're running dhcpd
on the same machine which is using dhcp client, then you will need to
disable dhcpd on that interface. By default, dhcpd will attempt to run
on every individual interface in the machine, this may cause you some
headaches.
	If, for example, you're internal network card was an Intel EtherExpress
(fxp0 for argument's sake), use this command to start dhcpd with the
same basic configuration as posted above.

'dhcpd fxp0'

	The short version: you gotta bind dhcpd to a specific interface if
running it on a multi-homed machine.
