[AYUDA] Problema con NATEO.

[carnoldo]

Estimados,
tengo funcionando un pfsense ya hace un buen tiempo y la verdad de maravilla.
Ahora se me presento un problema.
Tengo una placa de red conectado a una WAN, tengo una regla NAT para utilizar SIP y RTP. Eso marcha de maravilla, pero ahora se me presento un problema.
Mi red WAN es una red clase A, 10.0.0.0. La ip WAN mía es estática y es la siguiente: 10.2.76.231.
Todo el tráfico para VoIP (5060, 10000-20000) de la WAN a la LAN funciona bien exceptuando las IP WAN de la mi Subnet Wan (10.2.76.0/8).

Por ejemplo:
Si el paquete viene de la IP: 10.5.69.2, pasa sin problemas.
Si el paquete viene de la IP: 10.2.76.169, no pasa.

Les dejo una captura de paquetes para que vea cuando lo rechaza los paquetes:

Seguramente tienes marcada Block private networks en Interfaces - WAN.

A parte de esto tendrás que autorizar este tráfico en Firewall - Rules - WAN.
