vCloud Director Portal Access over IPv6

I got interesting question from a colleague if vCloud Director portal can be accessed over IPv6. I suspected the answer is yes so I had little bit of fun and did a quick test.

With NSX load balancer in front of my two VCD cells I created IPv6 VIPs for HTTP, HTTPs and VMware Remote Console (TCP 443) traffic and used the existing IPv4 pools. I also added these IPv6 addresses to my DNS servers so name resolution and certificates would work and was ready to test.

 

As I terminate SSL session on the LB and insert client IP into the header with X-Insert-For-HTTP I could observe both IPv6 and IPv4 clients in the vCloud Director logs:

Client coming from IPv6 fd13:5905:f858:e502::20:

Where 10.0.1.1 is load balancer internal interface. Remote Console proxy and OVF Tool also work.
