Need some help using miniupnp

Hey guys!
I have 2 routers:
Lan 1: (Openwrt)
go through
Lan 2: (Dont know)
I need ask the 'forward' to upnp server in uses a custon port 3333 and i cant change it.

I try on

upnpc -m eth0.2 -a 9093 9093 TCP
No IGD UPnP Device found on the network !

Perhaps because the port is not deafult.
Some hint?
Many thanks!

Does even have UPnP capability, and is that feature enabled? If asks to forward a port dynamically, but doesn't have UPnP available or enabled, it's unlikely to work as desired.
