You got a front end NAT. 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 126.96.36.199 (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
Issues on stability and advertisements of the port numbers
are not very different from those of addresses, which may
be assigned by DHCP.
