Hola

Estoy probando este firewall (OPNsense) basado en una distribución de FreeBSD.

Por ahora me ha gustado bastante la integración, en su versión 16.7R2, del IDS/IPS basado en Suricata.

Estaba configurandole el Force Safe Search Google en el servicio DNS resolver (deshabilité DNS forwarder).

Subí el fihcero forecegoogle.conf a la ruta /var/unbound/forecegoogle.conf
Con el contenido de todos los dominios de google haciendo un host override a la ip 216.239.38.120 del Force Safe Search google

Contenido de forecegoogle.conf :

En DNS resolver > Custom options > añadí: include: /var/unbound/forecegoogle.conf

Y salvé y reinicié el servicio.

Comprobé el fichero de conf de unbound, y ok

Desde una shell del firewall, me resuelve ok, haciendo host override de un dominio de google a 216.239.38.120

Pero si desde un equipo de la LAN resuelvo www.google.fr, no me hace el Force Safe Search Google.

Hola

Sí se me pasaba un detalle, tenia activada una openVPN y el equipo de la LAN me estaba resolviendo los dns vía el tunel.

Ahora ya me funciona el Force Safe Search Google en OPNsense.
