Detailed Description

This cmdlet sets the default policy for the specified host firewall. This policy specifies whether outgoing or incoming connections are allowed. At least one of the AllowIncoming and AllowOutgoing parameters must be set. When you configure the default firewall policy of an ESX/ESXi host version 5.0, you must provide the same value for the AllowIncoming and AllowOutgoing parameters.
