Yup, I did disabled the HTTPS/SSL option it doesn't register via uPnP (Ok fair enough, my router problem perhaps) and seems Ok with with manual registration (it doesn't return error) by port forwarding 9000.
I am using port forward 9000, and not port trigger 9000. Correct?
However, when I did a http://buffalonas.com/mynas from my local PC, I noted it is searching for an IP which is NOT my IP.
I tried it from PC from WAN side, it is the same incorrect IP.
I tried it from my Android over 3G, the cursor spins and returns COMM ERROR.
I am on Starhub cable.
