So I brought home a fancy Cisco router from work. At first, I had to 'test my connection' everytime I fired up the Xbox. I finally fixed that by setting static IP and DNS information on my Xbox. But now, i cannot get it to auto-sign-in to my Live account. I have made sure that option is enabled under my profile settings. I know that my NAT is moderate. Is this causing it not to auto-sign-in? I haven't had any other online problems so I haven't bothered forwarding any ports yet.
