Pi not answering on eth0 but OK on wlan0

[naoli]

Hello all,

My Raspi is working as a rooter on my LAN, it basically send the wifi connection through the ethernet card on which my LAN is connected :

<internet> ---- <wifi rooter> ---- <raspi on wlan0> --- <raspi on eth0> --- <LAN ethernet rooter>

It works great.

But when on my LAN with any PC, I can ping and ssh on the raspi through its wlan0 IP, but nothing on its eth0 IP.
How can I fix it ?

Here is my interfaces file :

Code: Select all

pi@raspberrypi ~ $ cat /etc/network/interfaces
auto lo

iface lo inet loopback

auto eth0
#iface eth0 inet dhcp
# the internal (wired) network interface
 allow-hotplug eth0
 iface eth0 inet static
  address 192.168.1.99
  network 192.168.1.0
  netmask 255.255.255.0
  broadcast 192.168.1.255
  gateway 192.168.1.99

# the external (wifi) interface
wireless-power off
auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
 address 192.168.8.99
 netmask 255.255.255.0

Many thanks for your help

i am not exactly sure, what you want...
you know, that you are on different subnet regions with using
eth0 (192.168.1.99) and
wlan0 (192.168.8.99)

Problem is on 192.168.1 Ethernet lan I can't ping or ssh the Pi on 192.168.1.99
Whereas I can ping and ssh on 192.168.8.99 (which is another subnetwork!)
Any machine on the Ethernet 192.168.1 subnetwork should be able to ping 192.168.1.99

Any idea how to fix this ?

Many many thanks

in the past i had sometimes networkproblems, when i was using "broadcast" and "network" to the interfaces files explicitly.
only use "address", "netmask", "gateway" and "nameserver", thats enough.

did you tried this...?
comment out
# broadcast ...
# network ...

I think the problem may be to do with your IP addressing being set up as two networks with no bridging between them - ie your pi knows about both networks but hasnt been told how to pass info between them.
