gderf -- I expect that you are right, no firmware update is needed. Either that, or OBiTalk doesn't have my firmware version so doesn't know whether or not an update is needed, for the same reason that the Status/System Status doesn't display the last 2 fields (HardwareVersion and SoftwareVersion). I clicked on the (E) icon to get "Advanced Configuration", then System Status under Status, and only get the first 4 fields. Is there a different way to get there?
giqcass -- My OBi202 has an OBiWiFi plugged into it, which communicates via WiFi to my AT&T-supplied 2Wire router. So the OBi202 is not acting as a router. I don't see why the OBi would then think that my LAN is a WAN, but that did the trick, enabling me to connect to the OBi202 from a browser.
Does this cause my OBi202 to become vulnerable to network attacks from outside (i.e. real WAN)? Is such an attack on the OBi likely? If so, that means I should leave it enabled for as short a time as possible.
