Microsoft introduced a new technology to replace LSP, NDIS called WFP from https://msdn.microsoft.com/en-us/library/gg156122.aspx.

Am writting an applicatio based on Windows Filtering Platform, in visual studio 2017 for DNS interception and redirection.

Since Windows Filtering Platform is based on c++.

My question is this which version of c++ should i target for my c++ syntax.

Knowingly fully well that c++11 sysntax is different from c++2003 syntax.

Your response is needed

Thank you

1. class PacketFilter
2. {
3. private:
4. // Firewall engine handle.
5. HANDLE m_hEngineHandle;
7. // Firewall sublayer GUID.
8. GUID m_subLayerGUID;
10. // List of filters.
11. IPFILTERINFOLIST m_lstFilters;
13. // Method to get byte array format and hex format IP address from string format.
14. bool ParseIPAddrString( char* szIpAddr, UINT nStrLen,
15. BYTE* pbHostOrdr, UINT nByteLen, ULONG& uHexAddr );
17. // Method to create/delete packet filter interface.
18. DWORD CreateDeleteInterface( bool bCreate );
20. // Method to bind/unbind to/from packet filter interface.
21. DWORD BindUnbindInterface( bool bBind );
23. // Method to add/remove filter.
24. DWORD AddRemoveFilter( bool bAdd );
26. public:
27. // Constructor.
28. PacketFilter();
30. // Destructor.
31. ~PacketFilter();
33. // Method to add IP addresses to m_lstFilters list.
34. void AddToBlockList( char* szIpAddrToBlock );
36. // Method to start packet filter.
37. BOOL StartFirewall();
39. // Method to stop packet filter.
40. BOOL StopFirewall();
41. };
Follow these steps to use the PacketFilter class in your application:
- Instantiate an object of PacketFilter class.
- Add IP addresses to be blocked using the public method PacketFilter::AddToBlockList.
- Start the firewall using PacketFilter::StartFirewall public method.
- Finally, terminate the firewall by calling PacketFilter::Stopfirewall public method.
