I have an asus router working as a repeater (not bridged) and it would be really nice to have a uPnP forwarder on it.
I do not have access to the main router, but it does have uPnP turned on. So the idea is to have the reapeater forward upnp request to the main router to open up a port.
upnp client requests to open a port on the repeater -> repeater opens up a port -> upnp client on the repeater requests to open the same port on the main router.
Is it possible to do this or maybe someone has already done it in the past?
