You got 3 boxes behind it that all want to listen for inbound connections on port 49734. Let me know how that works out for you.It's just like your box can't listen for inbound connections at address 131.112.32.132 (address of my box). However, if UPnP box is configured properly, your box behind it can listen for inbound connections on some ports at some public address.
No, you said specifcially that it can be restored by end system*S* plural. Yes, I can get one box listening. Now tell me how to get the second and third boxes listening on the same port. If you can't do that, then in fact, it is *not* possible to restore *full* end-to-end connectivity.
