Explico algo mas lo que quiero hacer, por si estoy cometiendo algun otro error.
Necesito que los equipos de la red 192.168.5.x/24 y los equipos de la red 192.168.4.x/24 puedan imprimir a la impresora en red 192.168.5.50/24.
Pero que los usuarios de 192.168.5.x/24 solo puedan navegar por ether1 y ether2 (pcc)
Y los usuarios de 192.168.4.x/24 solo naveguen por ether3
este es el rsc algo mas claro
