upnpc port Forward

[emme]

I recently discovered the upnpc utility to perform a port forward on the network.

This is quite useful if you want to control (even remotely) a port forward.

My intention is to add a switch that will open/close a specific port for a remote appliance using a .sh script

Unfortunately my fritz 7490 won't open a port for an IP different than the requester (return code 606 - Not Authorized)

is there someone here who already handle this issue?

thanks
