Hi everybody

 

I use a Deco X20-4G in router mode behing my internet modem.

My internet moden manage its own network in 192.168.1.0/24 IP

My Deco settings seem OK, but let's take a look

 

My Deco has a static IP 192.168.1.7 in the internet modem network and internet settings are OK : 

   - default gateway : 192.168.1.254 => the modem

   - subnet mask : 255.255.255.0

 

The Deco manage its subnet in 192.168.68.0/24.

in LAN IP Section is :

  - IP : 192.168.68.1

  - subnet mask 255.255.255.0

 

The default settings for Deco DHCP section are selected.

 

All devices in the modem subnet and in the deco subnet work normally and can reach internet 

All devices in each subnet can communicate with the other device in the same subnet

All devices in the Deco subnet can communicate with the modem subnet.

 

But a device (for example a RaspberryPI in 192.168.1.24) in the modem subnet can't reach a device in the deco subnet (for example a NAS in 192.168.68.113). Normal I didn't configure a route to the deco subnet with the deco as Gateway

 

So I added a route in my RPI in the modem network : 

 

route add -net 192.168.68.0/24 gw 192.168.1.7 

 

and the result : 

 

pi@raspberrypi:~ $ route
Table de routage IP du noyau
Destination      Passerelle          Genmask           Indic Metric Ref    Use Iface
default             192.168.1.254    0.0.0.0               UG    202    0        0 eth0
192.168.1.0     0.0.0.0                255.255.255.0   U       202     0        0 eth0
192.168.68.0   192.168.1.7        255.255.255.0   UG     0        0        0 eth0

 

But I still can reach the NAS from the RPI

 

Neither with a ping : 

 

pi@raspberrypi:~ $ ping 192.168.68.113
PING 192.168.68.113 (192.168.68.113) 56(84) bytes of data.

Nor with a traceroute : 

 

pi@raspberrypi:~ $ traceroute 192.168.68.113

Deco is normaly used as gateway but it seems that the Deco does't manage IP gateway from the modem subnet to de Deco subnet.

While it manages it in the other way

Did I forget a setting ?

 

Could you help me ?

For information, i don't want to change the mode to choose the Access Point Mode.
