Together, these sound to me like a routing issue. Can you ping the NFS
server from the clients? Can you ping the clients from the server? It
sounds as if packets can make it from the clients to the server, but not
the other way. (netstat -rn)

Does rpcinfo work if you run it on the server itself? (rpcinfo -p)

Do any of the networks involved have funny MTUs? (netstat -in)

Is there a firewall somewhere?
