James wants to know if DSL Exteme's router will work with XBox Live. Leo says that it will work with all internet services. XBox Live configures the router to use Universal Plug n Play, and that's a security issue. So he'll want to use port forwarding to get around that and keep UPnP disabled. There may be a bit of latency, but DSL has less latency than a cable provider.
