Are all three exposed to the outside world, or are they already behind
some sort of firewall? (Not that being behind a firewall at a university
is any guarantee of security...) It would help to know a little more
about your general setup - how things are connected to the outside
world, what sort of firewalling is turned on, etc.

If you need a firewall, you will have to poke a hole in it for NFS.
You can and should do this selectively of course.

There have been discussions of similar problems in these newsgroups
recently, but it seems that Google doesn't archive them anymore.

It's actually all there in "man iptables", though it may seem like
trying to understand how a submarine works by reading the blueprints...
There is actually some Dutch documentation on www.netfilter.org.
Also assorted tutorials.
