I just read the following article about VEPA (Never heard of it before):
One thing that crossed my mind is VMware NSX, which seems to cover the features described in the article.
Hairpinning and security of virtual networks inside VMware is (presumably this year) covered by NSX.
And, it's embedded inside your hypervisor instead of an addon or extra module (hard- and software)
Maybe you should look into that! 😃
