Yes, but it's only half the problem.  You need to configure the NFS
server to be firewall friendly, too.  It's not, by default.  I don't see
any advantage in that, either.

I would have thought, that by now, Fedora's defaults would be for NFS to
be configured to use NFS4, and use fixed ports.  The firewall offers a
NFS4 prepared solution, but the NFS server does not.

I like to use autofs, so that accessing /net/servername/exportname/path
automatically mounts and provides access.  But for that to work, I've
either got to trust a large range of ports, trust ALL LAN traffic, or
reconfigure the NFS server.  I can't put mounts in the fstab file,
because some computers aren't always part of the LAN.
