most all routers work the same. different brands may use a few different addresses to enter them, but theres ony really 2 or 3 common ones that can be googled.
the router model almost don't matter at all. once your inside any router, just find a tab/section that is for port forwarding. they all work the same.
one model compared to another model of the same brand really wont be much different, other then the layout of the buttons
