Leaking connections on port forwarding (NAT) using Windows

[PitterW]

I have problem with my installation of VirtualBox (4.2.12) on which I run Ubuntu 32bit (host is Windows 7 64 bit) On top of Ubuntu I installed PostgreSQL and forwarded ports for accessing DB using NAT, I also setup host-only interface. I connect to postgres from windows using Tomcat, when I kill tomcat application connections established with DB remain "established" although they are dropped from host side(Windows). When I use host-only interface I don't see this kind of problems, dropped connections are also dropped from guest.

I test same scenario on Mac and it seems to work just fine on NAT.

Please reopen if still relevant with a recent VirtualBox release.
