Looks good to me.

I have no idea what you mean by "there isn't anything at the /net/ 
link". But what happens if you try to mount your one of the exported 
directories from the other machine?

sudo mount -tnfs 192.168.71.3:/ /mnt

Provided that 192.168.71.3 is the machine which runs the nfs server. 
BTW: In your exports file the IP address specifies which host is allowed 
to mount the share and it should be either one host (like 192.168.71.3) 
or a IP range like 192.168.71.0/24 - I have no idea what would happen if 
you use a host address with a trailing /24.
