I have fedora 20 machine which i am using as a router. it has two lan cards, p2p1 (external) and p6p1 (internal). I would like to test some servers from within the local network but by using the public ip address given by ISP. It does not work now. I realize i need some kind of nat loopback or wan redirection to work. Can someone please tell me how i do this with firewalld?
