linux filesystem integration not working (nfs timeouts)

Hi,
I'm trying to setup Wualas filesystem integration. Unfortunately there is very little info on this.
I have this in my fstab:

localhost:/wuala/ /home/user/wuala/wuala/direct nfs user,noauto,rsize=8192,wsize=8192,timeo=14,intr,nolock,soft

When i start wuala, and then try to mount the volume i get:

mount: mount to NFS server 'localhost' failed: timed out (retrying).
mount: mount to NFS server 'localhost' failed: timed out (retrying).
mount: mount to NFS server 'localhost' failed: timed out (retrying).
mount: mount to NFS server 'localhost' failed: timed out (retrying).
mount: mount to NFS server 'localhost' failed: timed out (giving up).
Wuala does not give any meaningful logs:

Network drive status -> service started + portmap running, log says:
Debug log initialized
Starting server Mount ...
Starting server NFS ...

Wualas server seems to run nicely:

user@host:~/wuala/wuala$ rpcinfo -p

Any ideas on this?
Thanks in advance.
