Nfs Share within container

Hi,

I wonder if someone could help,

I currently have a nas with OVH (1tb) which is connected via a private ip 10.*.*.* address, the Share works fine within the container but we are moving away from the nas to one of the backup servers they offer.

I have installed nfs server on the backup server and have managed to setup a share to the proxmox hardware host e.g prox1

When I try to setup the container which currently has a working nfs share (see below for the fstab)

10.*.*.*:/nas-000000/backup /mnt/backup nfs rw 0 0

Which works fine, When I try to add my new nfs server using the following

mount -t nfs 37.187.130.15:/home/dump /mnt/backupserver

I get the following error


mount.nfs: Protocol not supported

So I decided that maybe I need to have the nfs share mapped as NFS, when I go into the gui and add new storage, select NFS, enter ip, the mount point displays, But when I go to view the content I get the following error

mount error: mount.nfs: Operation not permitted (500)

The /etc/exports on the nfs server looks like the below, with the /etc/hosts.allow as follows.


/home/dump 178.*.*.*(rw,sync,no_subtree_check,no_root_squash) 178.*.*.*(rw,sync,no_subtree_check,no_root_squash) 178.*.*.*(rw,sync,no_subtree_check,no_root_squash)


rpcbind: 178.*.*.*, 62.*.*.*, 178.*.*.*, 178.*.*.*



Does any one have any idea what I am doing wrong, I can't seem to work out what the problem is.
