I have a NAS box setup at a different location than our company. The idea was to use it as offsite backup. When the NAS box was on our LAN we had no issues mounting the NFS shares. Once we moved it to the offsite location we are unable to talk to it.
So far I have forwarded ports (tcp and upd): 2049, 111, 1110, 4045
Every command such as rpcbind, showmount and mount itself all report connection timed out.
It has become increasingly hard to determine where I am being firewalled. Can anyone point out some tips. What ports do I need to open at the offsite location and which ports need to be forwarded at our main location?
