NFS Shares not working - FreeNas 8.0.2

[siterack_net]

I am trying to setup and NFS mount on a FreeNAS server, to offload my cpanel backups.
However, when I try to mount the NFS drive, I get:
mount -v /backup
mount: trying 192.168.1.117 prog 100003 vers 3 prot tcp port 2049
mount: trying 192.168.1.117 prog 100005 vers 3 prot udp port 702
mount.nfs: Input/output error
(MY FSTAB= 192.168.1.117:/mnt/TEST2 /backup nfs defaults,noauto 0 0)

On a different test, I was getting:
mount -v /backup
mount: trying 192.168.1.117 prog 100003 vers 3 prot tcp port 2049
mount: trying 192.168.1.117 prog 100005 vers 3 prot udp port 702
mount: 192.168.1.117:/mnt/TESTING/nfs failed, reason given by server: Permission denied
(MY FSTAB= 192.168.1.117:/mnt/TESTING/nfs /backup nfs defaults,noauto 0 0)

FreeNAS is set to allow NFS services through the firewall.
I set the NFS mount to allow the IP of 192.168.1.106 (the cpanel server)

Can anyone explain what I am doing wrong here?
Specifically, am I formatting the fstab incorrectly, or what are the specific Items I need to set in FreeNAS 8?
I followed the documentation, and it just doesn't work. I've never worked with NFS before, so a step by step would be great.
