• This alert is supported only for the NSX-V distributed firewall rules, NSX-T distributed and Edge firewall rules, and NSX-T on VMware Cloud on AWS firewall rules. Other firewall vendors are not supported.
• The following firewall rule properties are currently supported for masking computation:
  • Source
  • Destination
  • Applied To
  • Service protocol and Port ranges
  • Packet type
  • Layer-7 application IDs
• Rules with source or destination inversion are not supported.
• Disabled rules are ignored.
• Rules with security groups containing excluded members directly or indirectly in Source/Destination or Applied To is not supported.
