MikroTik RouterOS v6.36 [current] publicado

Hace unas horas fue publicada la versión v6.36 de la rama current del RouterOS con importantes cambios y agregados.

Uno de los agregados importantes es una relacionada con el firewall y al diagrama de flujo de MikroTik. Se ha agregado un nuevo «chain» previo al connection tracking llamado «raw prerouting» que ayudará a proteger al connection tracking de tráfico innecesario.

Adicionalmente se le ha agregado la opción de agregar un nombre de dominio para los address-list.

También se le ha adicionado el soporte para IPFIX (IP Flow information Export) (RFC5101 y RFC5102), algo que es de mucha utilidad para los administradores de red, ya que permite monitorear y controlar la red de manera mas eficiente.

La extensa lista de cambios también habla de IPSec, LTE y demás que la detallamos a continuación:

*) arm - added Dude server support;
*) dude - (changes discussed here: http://forum.mikrotik.com/viewtopic.php?f=8&t=110428);

*) firewall - allow to add domain name to address-lists (dynamic entries for resolved addresses will be added to specified list);
