NFS has versions 2,3,4. Your advanced Fedora setup probably defaults to 4.
You can try the following (/etc/fstab format) or set the options in a
server:/export /mnt nfs nfsvers=2,proto=udp 0 0
Also, NFS by default uses random ports. I don't remember the exact
format, but there are 4 settings in /etc/sysconfig/nfs, XXX=4000, etc.
We use 4000-4004 on systems at work. That probably doesn't matter if
you have stopped selinux and firewalls on both sides. Also be sure
that portmap is started or you won't get anywhere.
If you fill your heart with regrets of yesterday and the worries
of tomorrow, you have no today to be thankful for.
