Service IP or Pod IP not reachable using OpenShift SDN on top of VMware NSX VXLAN

Solution Verified - Updated -


  • Service IPs do not seem to be accessible from some nodes in the cluster
  • For example, when we try to deploy an application, an image fails to download from the internal registry with a "no route to host" error
  • Unable to communicate to or from pod IPs between container nodes and infrastructure nodes, where one node is on VM and a different node is bare-metal/physical host.
  • Can we change the SDN port 4789?


  • OpenShift Container Platform 3.x
  • OpenShift SDN over NSX SDN
  • VMware with using NSX SDN version 6.2.3 or later
  • VMware with using NSX SDN version 6.2.2 and older and migrating to NSX SDN 6.2.3 or later
