According to Microsoft[1,2], raw socket support exists, however
restricted to ICMP and IGMP protocols (and, maybe, UDP). I actually
created a raw socket ping in VB.NET, very similar to this one.
Anyway, a recent post shows in C# that you actually can craft tcp
packages for raw sockets (I assume XPSP2 here). If this works in C#,
I don't see why it should not work for VB.NET. Be careful with the checksum,
which is not as trivial as with ICMP packages. I made one a while ago
(in c, but you may be able to port it to VB.NET).
Cheers, and keep us updated.
