[SOLUCIONADO] Squidguard para varias subredes

MichelR

Hola a tod@s, tengo una duda con squidguard. Tengo creadas 2 subredes 172.26.0.0/24 (LAN) y 172.26.1.0/24 (WIRELESS), esta última con DHCP de pfSense, hasta aquí todo bien, se navega desde ambas redes y con squid puedo filtrar, pero… siempre hay un pero, con squidguard no me filtra nada en la red wireless. Es que squidguard sólo funciona para la red LAN ? tengo squid 3 y squidguard.

Un saludo

acriollo

Hola, tienes especificado en el squid que escuche para las dos redes ?

en squidguard tienes dado de alta algun target para la red wireless ?

puedes colocar aqui la config de tus servicios ?

Saludos

MichelR

Hola acriollo, si tengo especificado las dos redes. En cuanto al tema del target tengo definidos varios en squidguard con páginas aceptadas y bloquedas.

Todo lo estoy haciendo desde la gui.

El caso es que squid si filtra bien para las dos redes, el problema es squidguard que pasa de la red wireless, seguramente me falte algo en la configuración. Llevo poco tiempo con pfSense y me falta mucho por aprender.

Según veo solo tienes reglas para una red por lo que todo tu trafico que no cae en este target se va a tu acción por default.

Revisa tu política por default para el acceso fuera y dentro de los horarios de restricciones.

Colocar un de y all como porlitca por default y verifica si todo el trafico se va por ahí.

Saludos

MichelR

Muchas gracias acriollo!!

Efectivamente no tenía definido el target para la segunda red. Vamos aprendiendo poco a poco…

Un saludo

acriollo

que bien!

Edita el titulo y agregale [RESUELTO] para que otras gentes sepan que lo pudiste resolver.

Saludos

huaressa

yo tengo el mismo problema sera que puedes poner en pantalla tu solucion, desde ya gracias

acriollo

El tema aqui huaressa es que este usuario no tenia reglas para la segunda red en el squiguard, por lo tanto se va a a la politica por default. Si la politica por default es denegar , eso hace el sistema.

Tambien hay que verificar que tenga salida por lo menos de DNS la red que quieres que salga.

Hola acriollo, perdon por mi ignorancia pero en donde se declaran las demas subredes ? Me podras guiar?
