Problem with nfs rw

I set up my /etc/exports file on the lacie like so
/share/1000/public 192.168.0.1/24 (rw,sync,no_root_squash,no_subtree_check)
Then on my ubuntu installation I added this line to fstab
192.168.0.150:/share/1000/public /media/NETWORKHD nfs _netdev,rw,auto 0 0
I can read from the share just fine but I cannot write to it (I need to be able to add,read and delete files/directories). I get this message
touch: cannot touch `ok': Read-only file system
How do i solve this?
