I'm still trying to decide if I'm getting this or not (decided to skip the beta), but have a question I'm hoping someone can answer. My current DSL "Modem" is a Cisco 675. The 675 has a built in DHCP server so does routing for me. It's hooked into a 10/100 switch. Now if I was adding another PC it'd be as simple as running a cable from the switch to the PC and the 675 will assign an IP. I'm wondering if this type of setup will work for XBL or not? I'm assuming it would, but was hoping someone has a similar config using a 675 or 678 and could comment. TIA!
