You can read all about the Pseudo Header and why its used in the checksum calculation by reading our article : www.firewall.cx/tcp-analysis-section-5.php

Please note, I've also removed your double post in the Cisco Lab as its obviously not the best place to ask about the pseudo header :)


I'm confident the above article will answer all your questions.
