My target is to allow only specific ips to connect my computer. I google it. Most of people are saying this work should be done in C not C#. I think we can import DLL in C# so it may be possible to write firewall in C#.
I found packet filtering api from msdn. But i was unable to understand those api. You can find these api http://msdn.microsoft.com/library/de..._reference.asp.
Is this possible to import those api in C# and write a code which can fulfill my requirement?
