Yes, end to end connectivity is restored. However, that end to end connectivity is restored does not mean your boxes can use 131.112.32.132 nor port 49734.
Yes, I can get one box listening. Now tell me how to get the second and third boxes listening on the same port.
Perhaps, you misunderstand how end systems behind NAT must interact with UPnP or something like that to be able to restore the end to end connectivity. End systems behind UPnP boxes are allocated disjoint sets of global port numbers, only among which, end systems can use as their global port numbers. End systems can obtain information on port numbers they can use through UPnP or something like that. Thus, there is no port number collision at the global side of the UPnP box. Similar mechanism is described in draft-ohta-e2e-nat-00.txt Masataka Ohta
