I am in a lab environment and am trying to get my nfs to work.
without the firewall showmount -e works just find.
I have permitted nfs, and rpc through however nfs still does not want to work with the firewall up.
the /etc/sysconfig/nfs file use to have a may ports configured in the same range of 400x however if I look at that file on this redhat 6 system the ports are different in the file.
There seems like there should be some sort of easy way to securely let nfs in
