Sort of not a whole bunch though.

Hi i've recently started a private tekkit server with me and my friends. But it seems like every time they join they have to use my private computer ip and/or my hamachi ip. I just want to know how to make a server where they can connect to my public ip. I searched a lot of videos but they are no help. I am also on a mac. So can someone please respond and help me out? Thanks!
