You will need a computer that will stay on 24/7 as well. You will need a DNS Server setup as well...which you may or may not have to pay for. There are a bunch of things you need to do, and not really anyone from DA to help you set it up. They have a forum which is your best chance at Customer Service. There is a guy over there, not an employee of DA that has helped others. I could never get mine to communicate! I'm going to buy a stand alone desktop to use primarily for this, and secondary for my girls to use.
Good luck, from what I gathered, it was easier for some routers more than others. For some, they could follow the directions on the Forum, and it worked. For others, a complete nightmare! You dang near have to be a Network guy, or have some good working knowledge of how to setup IP's and all that jive...IF you have a router that won't work right off the bat.
Good luck!!!
