DDF files are used only with OMA DM provisioning XML. Looking for the DDF XML files? See [CSP DDF files download](configuration-service-provider-reference.md#csp-ddf-files-download). ```xml ]> 1.2 Firewall ./Vendor/MSFT Root node for the Firewall configuration service provider. MdmStore Global PolicyVersionSupported Value that contains the maximum policy version that the server host can accept. The version number is two octets in size. The lowest-order octet is the minor version; the second-to-lowest octet is the major version. This value is not merged and is always a fixed value for a particular firewall and advanced security components software build. text/plain CurrentProfiles Value that contains a bitmask of the current enforced profiles that are maintained by the server firewall host. See FW_PROFILE_TYPE for the bitmasks that are used to identify profile types. This value is available only in the dynamic store; therefore, it is not merged and has no merge law. text/plain DisableStatefulFtp FALSE This value is an on/off switch. If off, the firewall performs stateful File Transfer Protocol (FTP) filtering to allow secondary connections. FALSE means off; TRUE means on, so the stateful FTP is disabled. The merge law for this option is to let "on" values win. text/plain SaIdleTime 300 This value configures the security association idle time, in seconds. Security associations are deleted after network traffic is not seen for this specified period of time. The value MUST be in the range of 300 to 3,600 inclusive. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, use the local store value. text/plain PresharedKeyEncoding 1 Specifies the preshared key encoding that is used. MUST be a valid value from the PRESHARED_KEY_ENCODING_VALUES enumeration. Default is 1 [UTF-8]. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, use the local store value. text/plain IPsecExempt 0 This value configures IPsec exceptions and MUST be a combination of the valid flags that are defined in IPSEC_EXEMPT_VALUES; therefore, the maximum value MUST always be IPSEC_EXEMPT_MAX-1 for servers supporting a schema version of 0x0201 and IPSEC_EXEMPT_MAX_V2_0-1 for servers supporting a schema version of 0x0200. If the maximum value is exceeded when the method RRPC_FWSetGlobalConfig (Opnum 4) is called, the method returns ERROR_INVALID_PARAMETER. This error code is returned if no other preceding error is discovered. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, use the local store value. text/plain CRLcheck This value specifies how certificate revocation list (CRL) verification is enforced. The value MUST be 0, 1, or 2. A value of 0 disables CRL checking. A value of 1 specifies that CRL checking is attempted and that certificate validation fails only if the certificate is revoked. Other failures that are encountered during CRL checking (such as the revocation URL being unreachable) do not cause certificate validation to fail. A value of 2 means that checking is required and that certificate validation fails if any error is encountered during CRL processing. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, use the local store value. text/plain PolicyVersion This value contains the policy version of the policy store being managed. This value is not merged and therefore, has no merge law. text/plain BinaryVersionSupported This value contains the binary version of the structures and data types that are supported by the server. This value is not merged. In addition, this value is always a fixed value for a specific firewall and advanced security component's software build. This value identifies a policy configuration option that is supported only on servers that have a schema version of 0x0201. text/plain OpportunisticallyMatchAuthSetPerKM This value is used as an on/off switch. When this option is false, keying modules MUST ignore the entire authentication set if they do not support all of the authentication suites specified in the set. When this option is true, keying modules MUST ignore only the authentication suites that they don’t support. For schema versions 0x0200, 0x0201, and 0x020A, this value is invalid and MUST NOT be used. text/plain EnablePacketQueue 0 This value specifies how scaling for the software on the receive side is enabled for both the encrypted receive and clear text forward path for the IPsec tunnel gateway scenario. Use of this option also ensures that the packet order is preserved. The data type for this option value is a integer and is a combination of flags. A value of 0x00 indicates that all queuing is to be disabled. A value of 0x01 specifies that inbound encrypted packets are to be queued. A value of 0x02 specifies that packets are to be queued after decryption is performed for forwarding. text/plain DomainProfile EnableFirewall 1 This value is an on/off switch for the firewall and advanced security enforcement. If this value is false, the server MUST NOT block any network traffic, regardless of other policy settings. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, the local store value is used. text/plain DisableStealthMode 0 This value is an on/off switch. When this option is false, the server operates in stealth mode. The firewall rules used to enforce stealth mode are implementation-specific. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, the local store value is used. text/plain Shielded 0 This value is used as an on/off switch. If this value is on and EnableFirewall is on, the server MUST block all incoming traffic regardless of other policy settings.

This value is valid for all schema versions. text/plain AllowLocalIpsecPolicyMerge 1 This value is an on/off switch. If this value is false, connection security rules from the local store are ignored and not enforced, regardless of the schema version and connection security rule version. The merge law for this option is to always use the value of the GroupPolicyRSoPStore. text/plain DefaultOutboundAction 0 This value is the action that the firewall does by default (and evaluates at the very end) on outbound connections. The allow action is represented by 0x00000000; 0x00000001 represents a block action. Default value is 0 [Allow]. The merge law for this option is to let the value of the GroupPolicyRSoPStore win if it is configured; otherwise, the local store value is used. text/plain DefaultInboundAction 1 This value is the action that the firewall does by default (and evaluates at the very end) on inbound connections.

PackageFamilyName FilePath FQBN ServiceName PackageFamilyName PackageFamilyName - This App/Id value represents the PackageFamilyName of the app. The PackageFamilyName is the unique name of a Microsoft Store application. text/plain FilePath FilePath - This App/Id value represents the full file path of the app. For example, C:\Windows\System\Notepad.exe. text/plain Fqbn Fully Qualified Binary Name text/plain ServiceName This is a service name, and is used in cases when a service, not an application, must be sending or receiving traffic. text/plain Protocol 0-255 number representing the ip protocol (TCP = 6, UDP = 17). If not specified the default is All. text/plain LocalPortRanges Comma Separated list of ranges for eg. 100-120,200,300-320. If not specified the default is All. text/plain RemotePortRanges Comma Separated list of ranges for eg. 100-120,200,300-320. If not specified the default is All. text/plain LocalAddressRanges Consists of one or more comma-delimited tokens specifying the local addresses covered by the rule. "*" is the default value. Valid tokens include: "*" indicates any local address. If present, this must be the only token included. A subnet can be specified using either the subnet mask or network prefix notation. If neither a subnet mask not a network prefix is specified, the subnet mask defaults to 255.255.255.255. A valid IPv6 address. An IPv4 address range in the format of "start address - end address" with no spaces included. An IPv6 address range in the format of "start address - end address" with no spaces included. If not specified the default is All. text/plain RemoteAddressRanges Consists of one or more comma-delimited tokens specifying the remote addresses covered by the rule. The default value is "*". Valid tokens include: "*" indicates any remote address. If present, this must be the only token included. "Defaultgateway" "DHCP" "DNS" "WINS" "Intranet" "RemoteCorpNetwork" "Internet" "PlayToRenderers" "LocalSubnet" indicates any local address on the local subnet. This token is not case-sensitive. A subnet can be specified using either the subnet mask or network prefix notation. If neither a subnet mask not a network prefix is specified, the subnet mask defaults to 255.255.255.255. A valid IPv6 address. An IPv4 address range in the format of "start address - end address" with no spaces included. An IPv6 address range in the format of "start address - end address" with no spaces included. If not specified the default is All. text/plain Description Specifies the description of the rule. text/plain Enabled Indicates whether the rule is enabled or disabled. If the rule must be enabled, this value must be set to true. If not specified - a new rule is disabled by default. text/plain Profiles Specifies the profiles to which the rule belongs: Domain, Private, Public. See FW_PROFILE_TYPE for the bitmasks that are used to identify profile types. If not specified, the default is All. text/plain Action Specifies the action for the rule. Type 1 Specifies the action the rule enforces: 0 - Block 1 - Allow text/plain Direction IN Comma separated list. The rule is enabled based on the traffic direction as following. IN - the rule applies to inbound traffic. OUT - the rule applies to outbound traffic. If not specified the detault is IN. text/plain InterfaceTypes All String value. Multiple interface types can be included in the string by separating each value with a ",". Acceptable values are "RemoteAccess", "Wireless", "Lan", "MobileBroadband", and "All".

The EdgeTraversal property indicates that specific inbound traffic is allowed to tunnel through NATs and other edge devices using the Teredo tunneling technology. In order for this setting to work correctly, the application or service with the inbound firewall rule needs to support IPv6. The primary application of this setting allows listeners on the host to be globally addressable through a Teredo IPv6 address. New rules have the EdgeTraversal property disabled by default. text/plain LocalUserAuthorizedList Specifies the list of authorized local users for the app container. This is a string in Security Descriptor Definition Language (SDDL) format.. text/plain Status Provides information about the specific verrsion of the rule in deployment for monitoring purposes. text/plain Name text/plain ```
