El conjunto original de programas iptables, incluidas ip6tables, arptables y ebtables, fue clasificado como obsoleto en 2018 y ya ha sido reemplazado por nftables en la mayor\u00eda de las distribuciones.    <\/p>\n<p>En la nueva versi\u00f3n:  <\/p>\n<ul>\n<li class=\"l\"> La utilidad iptables-nft ha implementado el soporte para la adici\u00f3n y reemplazo at\u00f3mico de reglas en una sola transacci\u00f3n.        *filter     -A FORWARD -m comment --comment 'nueva regla siendo reemplazada'     -R FORWARD 1 -m comment --comment 'nueva regla reemplazante'  COMMIT\n<li class=\"l\"> En la utilidad xtables-monitor se ha agregado el soporte para reconocer operaciones de eliminaci\u00f3n de cadenas b\u00e1sicas (INPUT, FORWARD, OUTPUT) y en este caso se muestra el comando 'iptables -X nombre_cadena'.\n<li class=\"l\"> Se ha asegurado la traducci\u00f3n al formato nftables de las reglas con el protocolo '-p sctp', pero sin especificar expl\u00edcitamente el m\u00f3dulo '-m sctp', como se hace para TCP y UDP (basta con indicar '-p tcp' o '-p udp', y '-m tcp' o '-m udp' se aplicar\u00e1 autom\u00e1ticamente).\n<li class=\"l\"> Se ha a\u00f1adido soporte para los paquetes ICPM info-request e info-reply.\n<li class=\"l\"> Se han corregido errores en las utilidades iptables-translate e ip6tables-translate, utilizadas para convertir reglas en nftables.
