I've been trying everything for many hours. What i want to acchieve is simple to describe, let me show it in an image:
I have a computer (running Windows 7, but it should be the same for any OS) . The target PC doesn't have USB so i cannot plug a dongle.
I have a raspberry pi 2B, with a fully working dongle, up and running latest raspbian and connected to the LAN through wlan0.
What is needed is simply to connect the target computer to the LAN through RPI's wifi dongle. The IP of the target PC will be set by the DHCP of the LAN. Same goes to the internet connection. The target PC should have access to the LAN's resources (printers, files, etc)
I thought that bridging wlan0 and eth0 should do the trick, but the br0 (bridge interface created) doesn't seem to connect to the LAN wifi , i don't know why. I also tried ibtables without success (among many other ideas that are floating through the web).
Any help would be greatly appreciated.
