how to route internet traffic between wifi and ethernet port on macbook pro
I want to set up routing trafic between the wifi and the ethernet port on my macbook pro. The scenario is like this I have a wifi internet poit to which i connect using the macbook. Then I have an old computer without wifi but with ethernet port wich i will wire into the macbook. Once I have set up the routing on my macbook i should be able to access internet on both computers.
How can i achieve this?
Thanks
