Problema con 2 placas de red

[vane_bdm]

Hola a todos: tengo un servidor al que le instale un debian squeeze.
Tiene 2 placas de red, una para conexion con Internet y la otra para la red interna.
La de la configuracion a internet funciona barbara pero la otra no, les paso el archivo interfaces a ver si ahi le estoy errando

Código:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0

iface eth0 inet static
address 200.xxx.xxx.20
netmask 255.255.255.0
network 200.xxx.xxx.0
broadcast 200.xxx.xxx.255
gateway 200.xxx.xxx.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 200.xxx.xxx.xxx 200.xxx.xxx.xxx

auto eth1
iface eth1 inet static
address 192.198.0.50
netmask 255.255.255.0
network 192.168.0.0


Tambien hice las siguientes pruebas

sudo route
Código:

Si hago ping a la eth0 que es de internet responde de 10.
En cambio con la eth1
ping 192.168.0.50
PING 192.168.0.50 (192.168.0.50) 56(84) bytes of data.

se queda ahi.... no hace nada
Alguien me puede decir que puedo hacer? que tengo mal?

Saludos y gracias
