Ubiquiti AirOS v5.5 publicado

El 10 de Abril fue publicado el firmware que tanto se había estado haciendo esperar, la versión v5.5 del AirOS. En el listado de changelog hay una gran cantidad de agregado y soporte interesantes.

Este release ya soporta los nuevos modelos Bullet M2 y M5 Titanium. Nuevas funcionalidades importantes como el soporte de administración de Vlans, la opción de UPnP (Universal Plug and Play) para equipos en modo Router SoHo ya está disponible.

Como era de esperar ya los equipos empiezan a soportar IPv6, que sumado a los avance que ha tenido MikroTik en éste sentido, ya se pueden ir desplegando redes tipo Dual-Stack sin problemas para abordar el problema de los pocas IPv4 disponibles.

He resaltado los cambios que mas me llamaron la atención:
