3.1.4.49 RRPC_FWAddConnectionSecurityRule2_10 (Opnum 49)

  • Article

The RRPC_FWAddConnectionSecurityRule2_10 (Opnum 49) method requests the server to add the specified connection security rule in the policy contained in the policy store referenced by the handle specified in the hPolicyStore parameter. The method is only supported for binary versions 0x020A and 0x0214.

 unsigned long RRPC_FWAddConnectionSecurityRule2_10(
   [in] FW_CONN_HANDLE rpcConnHandle,
   [in] FW_POLICY_STORE_HANDLE hPolicyStore,
   [in] PFW_CS_RULE2_10 pRule,
   [out] FW_RULE_STATUS* pStatus
 );

rpcConnHandle: This parameter is an RPC binding handle that connects to the RPC interface of the Firewall and Advanced Security Protocol.

hPolicyStore: This input parameter is an FW_POLICY_STORE_HANDLE data type. The data type MUST contain an opened policy store handle, successfully opened with the RRPC_FWOpenPolicyStore (Opnum 0) method. The handle MUST have read/write access rights.

pRule: This parameter represents the firewall rule that the client adds to the store. The rule MUST be a valid rule, as specified in the definition of the FW_CS_RULE2_10 data type.

pStatus: This output parameter is the status code of the rule as specified by the FW_RULE_STATUS enumeration. This field is filled out on return.

Return Values: The method returns 0 if successful; if it fails, it returns a nonzero error code. The field can take any specific error code value, as specified in [MS-ERREF]. The following return values are common.

Return value/code

Description

0x000000B7

ERROR_ALREADY_EXISTS

The specified rule has a rule ID that already exists in the specified store.

0x00000032

ERROR_NOT_SUPPORTED

The specified store does not support this method; the store might be read-only.

0x00000005

ERROR_ACCESS_DENIED

The hPolicyStore handle was not opened with read/write access rights. The error is also returned if the client does not have the required credentials to call the method.

0x00000057

ERROR_INVALID_PARAMETER

One of the parameters of this method either is incorrect, or is required and not specified. This error can be returned because:

  • The pRule object did not pass the firewall rule validations specified in the definition of the FW_CS_RULE data type.

  • One of the required values is not specified.

  • A policy store does not support rules with profile conditions other than ALL profiles.

Exceptions Thrown: No exceptions are thrown beyond those thrown by the underlying RPC protocol, as specified in [MS-RPCE]. If any lower-layer errors are reported by RPC exception, this exception is converted to an error code and reported to higher-layer protocols via the return value.

This method adds a firewall rule in the firewall linked list of the memory representation of the store being modified. It also writes through and saves the rule on disk. If called on an online store, the firewall rule is also enforced.

The server MUST validate that the client is authorized to perform the requested operation (as defined in section 3.1.4) before executing this method.
