So I'm basically trying to connect my Yun to a wifi connectoin(with internet) and then connect another device to the ethernet port to use said internet. Essentially what I am looking for is a network setup that is opposite to the default set up. I have a small diagram below to illustrate what exactly I'm talking about.
Generic router with internet acces <----->(wifi) Yun -------->(ethernet with internet) Other device(s)
I have a fair idea in the sense that I would need to set up the ethernet as a DHCP server but I'm not entirely sure of whole process and what exactly I need to do. Thanks in advance!
