I recently started a software security class. I expect to be required to craft and send packets; yet I read somewhere my Windows 8.1 installation filters packets based on a valid checksum. Is this claim true? Are there any other restrictions not found on a "standard" Linux distribution (such as Debian)? If any of these restrictions exist, can they be circumvented, and at what cost?
