Packet sniffing and modification

First, why do I need that? I have Wifi network. I want everyone that just connected to wifi first to redirect to login page and then if login is successful - redirect to the page requested. I thought to do that using PCap. But since WinPCap allows just to monitor packets, I can't stop packet from being sent to destination host. So the question is how can I sniff packet and change it content? As of beginning i want to capture HTTP packets only from specified network adapter.

That's really hard to do the way you describe - doing this on "packet level" will present several problems (among others performance!).

To achieve what you want you have several easier and better suited options:

  • use a proxy which handles the autentication part

  • build a proxy (see this for C# source code etc.)

For the proxy-based options you just need to configure the network in a way that all outbound traffic must use that proxy...
