The two Guest OS drivers that are required for the Identity Firewall to operate are NSX Network Introspection and Guest Introspection. NSX Network Introspection provides network-level visibility and control, while Guest Introspection provides kernel-level visibility and control. The other drivers listed, vmxnet3, NSX File Introspection, and e1000e, are not required for the Identity Firewall to operate.

This command allows you to display the current firewall ruleset configuration on an ESXi host. It will show the ruleset names, whether they are enabled or disabled, and the services and ports that the ruleset applies to.

For example, you can use the command "esxcli network firewall ruleset list" to list all the firewall rulesets on the host.

You can also use the command "esxcli network firewall ruleset rule list -r " to display detailed information of the specific ruleset, where is the name of the ruleset you want to display.

It's important to note that you need to have access to the ESXi host's command-line interface (CLI) and have appropriate permissions to run this command.
