What ports need to be forwarded for NFS to work?

I am tearing my hair out trying to get port-forwarding to work with
NFS (Network File System). I am running Ubuntu Feisty at home as a
media server. On my local network I can mount a NFS file no problem by
specifying the local address ( for example).
However, I also want to be able to mount an NFS file when I am away
from the house. I have set up port forwarding on my router no problem
for other services (ssh, apache, etc), but can't get NFS to work from
outside. I have read that NFS uses port 2049 and confirmed that my
system is indeed using that port for NFS. I can't find any information
on what other ports need to be forwarded. Do I need to forward ports
for mountd or something else? If so, what other services and what are
the ports?

Many thanks in advance,

Craig Hagerman
