# Freaky Flag Day

Author: @Kkevsterrr#7469

## What should we do?

Our TCP flags have decided that they'd like to change places today; all you need to do is reach the HTTP server!\
\
Roses are red, and SYNs are FINs too.\
RST+ACKs are now SYN+ACKs for you.\
ACKs are now Es, and what else have we done?\
PSH+ACKs are FIN+SYNs just for the fun.\
\

*Hint: If you want to run this challenge from your home or a VM, make sure you are not behind a NAT that could eat your unexpected packets.*\ <br>
