Adding 0.0.0.0/32 in /etc/exports does not seem to work. Is there some other configuration option that can be used for this?

Try

/filesystem      *

You might also try reading man exports, which has a set of examples at the bottom from which the above is derived. You may also wish to note that 0.0.0.0/32 means "only the IP address 0.0.0.0". It is possible that you wwanted 0.0.0.0/0, which means "any IP address", instead, but * should do as well.

The * works. Thanks. –  xkcd May 29 '14 at 11:46

If you do not specify a subnet restriction, then there isn't one. E.g.:

/filesystem -sec=sys,ro

Will allow anything to mount ro. Think carefully about whether you want to allow rw or root to anything on the network. (You may, but ... well, think about it first)
