Unidirectional network traffic or data diode emulation

[V1rtualHack3r]

Hi Folks, not sure if this is possible or not. But I would like to create an internal use only virtual switch with unidirectional traffic flow. i.e. I want to simulate a data diode connection between 2 virtual machines. To make this absolutely clear I need two VM's to talk in one direction only. Is it possible?

Any proper firewall should be able to do that, you should be aware that anything that is using TCP will not work, so it will break most applications.

Linjo, I disagree with the comment about any proper firewall will do that, firewalls are software based and susceptible to breach through bugs and poor config. As for the your TCP comment; of course I know that, that's the idea of diode, it's unidirectional, so traffic can go in and not back out. It's normally done through hardware but in this case it's a research job.

If anyone has any real suggestions or solutions to this then please feel free to post.
