I'm using Virtualbox 4.0.10 on a Debian Squeeze box. I have a Windows 7 VM that I use to host a game server. After setting up NAT and port redirection, clients can connect to the VM, but the game server shows it's getting connections from the NAT gateway IP (10.0.2.2). I need that the game server gets connections from the actual public internet client IP's, so I can set up an IP whitelist in the game server.
This Debian machine is directly connected to the internet. What can I do to make this work? Guess it's not VirtualBox problem and can solve that with a virtual network interface or so, but no idea how to do it. Guess it's not Virtualbox probmem and I can make it work with a bridge interface or so.
