Products

• VMware NSX for vSphere

Issue/Introduction

• NSX Edge NAT reports invalid configuration when multiple ports are used on the Load Balancer configuration
• You see the error:
  
  [Nat] Invalid NAT translated port parameter 80,81,82,83. Translated port must be an integer between 1 to 65535, or any
  
  Where the ports 80,81,82,83 match to a port list configured as a Virtual Server in the Load Balancing section of the Edge

Environment

VMware NSX for vSphere 6.3.x

Cause

This issue occurs every time you configure a Load Balancer virtual server with more than one port. Due to this, NAT becomes unmanageable while this configuration state exist for the affected Edge.

Resolution

This issue is resolved in VMware NSX for vSphere 6.4.0.

Workaround:

1. Remove the multi port mappings from the Load Balancer virtual server temporarily.
2. Make the necessary modifications to NAT.
3. Re-add the multi port mappings to the Load Balancer virtual server.
