For sake of confusion i will try and explain this the best i can. Lets just say i have a Cisco 4500 router. Now E0 is the outside world, E1 is my internal network, now what i want to do is add an OWA server on E3. I have it hooked up now but no connectivity, what kind of cable should it be crossover right?? And do i need to add a static route so i can access it internally and externally?
