[Question] IN-Out mode

HI!!

Thanks Xtr4nge for your work, and sorry for my bad english .

I Have some question, about mode In-Out...

I want (using wlan0 --> Internal wifi of Raspberry pi 3, and Wlan1--> Usb wifi ) use mi raspberry like a free wifi point, using mi conexion (wlan0) and creating the new one using the second lan (wlan1).

I think that we can do this, using the mode In-Out, but i have problems... because i can't see mi "free wifi" (wlan1) in other devide (laptop, and mobile phone)

Can you help me?

Thanks
