TKGIMC installed with NSX and both NSX Policy API and NAT mode enabled in the configuration.
However the NAT rules for OPS Manager, Bosh Director, Harbor and TKGi VMs appear to have been created with NSX Manager API when viewed through the NSX Manager UI. The NAT rules are actually created using Policy API but UI is incorrectly displaying them under Manager API.
NOTE: All NAT rules created for TKGi clusters use Policy API.
NSX prior to v4.2.4
This is a known issue in NSX that will be solved in NSX 4.2.4.
This issue will be resolved in NSX 4.2.4.
