    Let's say I have a home network of 3 computers, which share disks with
    NFS. What's the risk if all NFS-related ports are blocked on the firewall
    to the outside?

    There doesn't seem to be much of an alternative to NFS, or is it
    unreasonable to assume the internal net is trustworthy?
