hey all i am trying to set up windows apache on my computer but the problem is im connected to a router, so i can only access thhe page that I am hosting by typing in my internal IP from my computer. Now how do I set it up so that i can access the page from any computer by typing the external IP as the URL? I understand you have to forward port 80 or something? but then I heard most ISPs block that port.. so have to use port 81? I am using a Linksys Router.
