AT&T Internet Features

Have static IPs (5) with my own domain bound to a static IP. Initially my website was visible to the world but the past 3 weeks it is only visible within AT&T. Called customer support and they're faulting the BGW210 modem router box; in process of getting a replacement. Does it make sense to any

I do not know how to turn it on and I need it to play an online game with friends.
