URL for adding a NFS share:

nfs://10.0.0.2:/mnt/raid/space

URL for adding a samba file share:

smb://10.0.0.2/david

I simply left it in DHCP mode, and added the MAC address to my DHCP server so it would dish out the same IP address every time. That way my NFS sharing can be limited to that single IP address and not pose any security issues with floating or wide open shares.
