Maybe my picture isn't very clear, but my WAN access is on location A.
There's a router which receives an ip from the ISP. On the other side,
I'm having a 192.168.1.0/24 network

I tried this:
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth1
iface eth1 inet dhcp
wpa-driver wext
wpa-ssid ##SSID##
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk ##PSK KEY##
This configuration works fine. I'm receiving a DHCP offer from my router
(in location A)

So here it goes wrong. I didn't execute any other steps as step 2 fails
