There is no simple answer to this question, since it depends heavily on
what services you have, who you want to be able to access them, and what
your network topology looks like. I would suggest you read a good book
on firewalling concepts (e.g. [1]) before proceeding any further.

NFS is not supposed to traverse any firewall, since it does not provide
any kind of security mechanism whatsoever.
