Arturo Borrero, desarrollador de Debian, miembro del Coreteam del proyecto Netfilter y responsable de los paquetes relacionados con nftables, iptables y netfilter en Debian. propuso<\/a><\/noindex> traducir la pr\u00f3xima versi\u00f3n significativa de la distribuci\u00f3n Debian 11 para utilizar nftables por defecto. Si la propuesta es aprobada, los paquetes de iptables se convertir\u00e1n en opciones opcionales, no incluidas en la instalaci\u00f3n b\u00e1sica.<\/p>\n

El filtro de paquetes Nftables es notable por unificar las interfaces de filtrado de paquetes para IPv4, IPv6, ARP y puentes de red. Nftables proporciona en el nivel del n\u00facleo una interfaz general que no depende de ning\u00fan protocolo espec\u00edfico y ofrece funciones b\u00e1sicas para la extracci\u00f3n de datos de paquetes, realizaci\u00f3n de operaciones con datos y gesti\u00f3n del flujo. La l\u00f3gica de filtrado y los manejadores espec\u00edficos de protocolo se compilan en bytecode en el espacio de usuario, y este bytecode se carga en el n\u00facleo a trav\u00e9s de la interfaz Netlink y se ejecuta en una m\u00e1quina virtual especial similar a BPF (Berkeley Packet Filters). <\/p>\n

Por defecto, Debian 11 tambi\u00e9n propone utilizar el cortafuegos din\u00e1mico firewalld, que act\u00faa como una capa sobre nftables. Firewalld se ejecuta como un proceso en segundo plano, permitiendo modificar din\u00e1micamente las reglas del filtro de paquetes a trav\u00e9s de DBus, sin necesidad de reiniciar las reglas del filtro de paquetes y sin interrumpir las conexiones establecidas. Se utiliza la utilidad firewall-cmd para gestionar el cortafuegos, que al crear reglas se basa no en direcciones IP<\/a>, interfaces de red y n\u00fameros de puertos, pero de nombres de servicios (por ejemplo, para permitir acceso a SSH se debe ejecutar \u00abfirewall-cmd \u2014add \u2014service=ssh\u00bb, para cerrar SSH \u2014 \u00abfirewall-cmd \u2014remove \u2014service=ssh\u00bb).<\/p>\n
