INetFwPolicy2::BlockAllInboundTraffic property

Indicates whether the firewall should not allow inbound traffic.

This property is read/write.

Syntax


HRESULT put_BlockAllInboundTraffic(
  [in]   NET_FW_PROFILE_TYPE2 profileType,
  [in]   VARIANT_BOOL Block
);

HRESULT get_BlockAllInboundTraffic(
  [in]   NET_FW_PROFILE_TYPE2 profileType,
  [out]  VARIANT_BOOL *Block
);

Property value

True if the firewall should not allow inbound traffic.

Error codes

If the method succeeds, the return value is S_OK.

If the method fails, the return value is one of the following error codes.

Name	Meaning
E_ACCESSDENIED	The operation was aborted due to permissions issues.
E_INVALIDARG	The method failed because a parameter was not valid.
E_OUTOFMEMORY	The method was unable to allocate required memory.
E_POINTER	The method failed because a pointer was not valid.

Remarks

All interfaces are firewall-enabled. This means that all the exceptions (such as GloballyOpenPorts, Applications, or Services) which are specified in the profile are ignored and only locally-initiated traffic is allowed.

When you pass a profile type obtained from the CurrentProfileTypes property, make sure that you pass only one profile type to get_BlockAllInboundTraffic and put_BlockAllInboundTraffic. Note that get_CurrentProfileTypes can return multiple profiles.

Requirements

Minimum supported client	Windows Vista [desktop apps only]
Minimum supported server	Windows Server 2008 [desktop apps only]
