just play around the router till i found this thread. i ask the tm installer b4 wats the use of the remote. they said is next yr round april, there is a service upgrade to enable all port on the huawei MAN modem.

at the moment is just disable the remote management. but for the TR-09 not too sure yet of the functionality as yor site didnt mention bout the purpose of it and just disable it.

just my 2cents.
