Ubuntu 20.04, with IPTables firewall. Permito explícitamente puertos NFS dentro y fuera de los servidores. regreso (Se permiten sesiones relacionadas o establecidas)
He configurado puertos explícitamente en /etc/sysctl.conf para todos los servidores: fs.nfs.nlm_udpport=38073
fs.nfs.nlm_tcpport=38747
33333 configurado en el servidor kernel nfs
Los puertos 111,1110,2949,33333,4045,38073, 38747 están todos abiertos en el firewall de entrada y salida.
Cuando pruebo una montura, me sale esto:

Sin embargo, el mismo montaje en FSTAB se monta bien (durante el reinicio)
==== Editar =======
sin embargo... Si lavo IPTABLES, funciona... con el mismo mensaje "no existe tal"
