About me


Hello, Virtual World! My name is Sean Whitney, I graduated from Colorado State University in May 2012 with a Bachelor of Science in Business Administration concentrating in Computer Information Systems. I’m currently a Sr. Systems Engineer focusing on NSX and supporting products like Cloud Foundation, vRNI and AVI. I’ve been at VMware for almost 8 years and prior to being an SE I was an Escalation Engineer for NSX/VIO and Core vSphere. I have loved every bit of my tenure here at VMware and decided to start a blog to not only further my technical abilities, but help other virtualization enthusiasts through How To’s, Tutorials, New Releases, and Troubleshooting Deep Dives.

    we are using ESG as LB in One-arm mode. As application team wants to see the source-ip, we enabled transparent on pool.

    Now the application team is able to source-ip, but they lost the putty [ssh] access to all the pool servers. We changed the gateway of pool servers to LB ViP.

      If Transparent is not selected (default value), backend servers see the traffic source IP address as a Load balancer internal IP address. If Transparent is selected, source IP address is the real client IP address and NSX Edge must be set as the default gateway to ensure that return packets go through the NSX Edge device.

      since you have configured the NSX LB as one-arm Mode and the interface is connected as UP-Link for the NSX-LB the return trafic is blocked by the Edge appliance due to its State_full nature of traffic filtering.

      I mean the the client reached the Pool member with SSH session and the response was through the LB so LB drops the traffic, since it did not see the incoming traffic form the Client.
