Couple of tack-on questions....can these settings be accessed if the 502 is connected "behind" a router? This is the only way I can do it with ATT Uverse. Works fine, however, it appears that since the WAN port is connected to the router and gets a private ip via dhcp, I cannot connect via http over wan to the ATA....must be disabled, and only enabled via LAN port? I imagine I could temprarily connect a laptop there and hit it via lan address.

Real question is if doing this will allow me to set the adapter IP as static rather than dynamic? Or can customer service do that?
