My setup is the following:

- Smartphone (= client = victim)
- Laptop with Kali Linux
- iMac with Charles Proxy installed

If I set the iMac's IP and port 8888 in the WLAN-configuration on the iPhone, everything is redirected through the Charles Proxy and I can read username/password of a banking app (it's a client I'd like to prove the security hole).

How can I achieve the same behaviour with Kali but without setting the proxy in the iPhone configuration? Is it possible to tell all the clients in the network (except the iMac) to send their traffic through the iMacs IP with port 8888?

Thanks a lot!
