could you add a parameta to enter routers ip address

if you have more then one router in your network upnp isnt able to find the last one dealing with the internet. If i am in the same broadcast domain and it is the only upnp enabled router its fine but when ive got more then one upnp enabled routers or i am behind another router (that isnt doing any nat or filtering) it would be grate if i could use your little tool instead of having to log in to its web interface for just a basic overview/port forwarding.

I would be glad if you could add an -a address option where i can then type in e.g. 192.168.1.1 to specify the router i want to control.

thanks a lot in advance
