I have a Belkin N300 using Shibby 1.28 firmware.
My Raspbmc fstab looks like this:
proc /proc proc defaults 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620 0 0 /dev/mmcblk0p1 /boot vfat defaults,noatime 0 0 /dev/mmcblk0p2 / ext4 defaults,noatime 0 0 192.168.1.1:/tmp/mnt/Media /media/nfs-foo nfs _netdev,defaults,user,auto,noatime,intr 0 0
My NFS server settings are:
IP Address/Subnet: 192.168.1.3 (IP Address of my Raspbmc (Raspberry PI))
Access: Read only
Subtree Check: No
Other options: no_root_squash
I also tried the IP Address 192.168.1.0/24 & 192.168.1.0/255.255.255.0 for my Exports in Tomato, but I get the following error when I try and mount the share in SSH:
mount.nfs: access denied by server while mounting 192.168.1.1:/tmp/mnt/Media
The /tmp/mnt/Media path worked fine when I had it setup using Samba, but I can't get it to work with NFS.
