Not sure this is the right place to post this question.
My issue is actually simple, I have my android device using a data connection, and a hotspot setup on this device.
I connect my linux box to this hotspot, no problem.
My pc gets the address 192.168.1.234 on wlan0
My android device is 192.168.1.1 on wlan0
=> wlan0 UP 192.168.1.1/24
I can ping the local wifi addresses from both side. However, I cant ping a server located on internet from my pc.
I know there is something about forwarding the traffic from 1 side to the other but I cant figure out how to do it.
I did so far : On the android device
$ echo 1 > /proc/sys/net/ipv4/ip_forward
$ iptables -t nat -F
$ iptables -t nat -A POSTROUTING -j MASQUERADE
Nothing special on the pc except adding a route for a special server I want the traffic to go through the wlan0.

On the android side, I can see the traffic coming from my pc ie.

but never see a reply, like the packets would never go out of the android device.
What am i doing wrong?
Thanks for the help.
