I have configured NFS between two linux machines and the links work fine. I have to put the client machine behind a router and when I do that I am able to mount the NFS directories but when I try a simple command like "ls" the system hangs. I am not sure what ports I have to enable (It is a Linksys Router), right now I have ports 111,2049, 970:980, 32765:32769, 32823:32855 open on the router but still doesnt work. The output of the
"rpcinfo -p server" is as follows:

100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 32768 status

Any help would be appreciated.
thanks.

Are u able to do normal 'ls' to u r system directories(no NFS directories).

Hi thanks for the replies....regarding the first question...I do not have any problems running "ls" or any other command with non-NFS directories...and I am not sure what you mean by a link problem could you elaborate please (if its a physical hardware link you are talking about then I do not have any link problems)
thanks.

@cdeverapalli


Try this,


Please check with directories that u r exporting(on NFS server) on right place or not. That's they exist and at right place as same as entry made in /etc/export.
