It sounds like you don't have NFS properly setup to/from the 'other' host.
It would be easier to to understand you, if you broke the qn into multiple sentences and used specific hostnames, so we can figure out which is which.

Do you use NFS v3 or v4?
v4 requires port 2049/tcp
v3 requires the rpcbind port 111/udp or 111/tcp plus the ports configured in the rpcbind (as listed by command rpcinfo -p nfsserver)
