I can put the needed rules in the "RH-Firewall-1-INPUT" chain, but
mixing GUI administration and manual administration is undesirable to
prevent unexpected behavior, conflicts, etc, in the future. Is there
really no way to open the ports for NFS server other than by hand?
Opening NFS servers is tricky - the default GUI is too simple to do it
well.
You'll probably need to:
1) Learn about port "pinning" for NFS (so it always uses the same ports).
Since the GUI doesn't know about this, it doesn't solve the problem of
avoiding mixing GUI and manual firewall configuration, if I have to do
any of it by hand I'll do it all by hand, I'm dubious about using the
same rules for forwarding as INPUT anyway.
2) Use a fancier GUI, like firestarter (http://www.fs-security.com/), to
control your firewall.
As above. My preference is to do it all by hand, but it's disappointing
that the default Fedora tool doesn't work properly.
NFS is insecure anyways, so you'll want to have another firewall outside
the client network also. Do not expose the NFS server to public access.
Exports are to a very limited set of machines, and the rules I added by
hand don't allow others.
