Chances are the local router you removed provided a host name for a lookup for them machines, adding the machines to their respective /etc/hosts may solve it, as apparently NFS does a reverse DNS lookup (info found here: http://forums.freenas.org/showthread.php?7270-NFS-mount-times-out&p=29064&viewfull=1#post29064)

Hope that helps out.

Cheers,

Thanks very much for that. Adding the client's name and IP to the server's hosts file solved the problem. I didn't know about NFS's reverse hookup and hadn't come across that thread. Thanks for your help

Linux and Unix do reverse dns lookups for ftp, nfs, telnet, ssh, ...
