Getting around network restrictions started my software engineering career. You had to learn all about TCP/IP, transparent proxies, SSH tunnels, DNS, Linux boxes, /etc/passwd, /etc/shadow, John The Ripper, write Perl scripts, cron jobs, CGI, how automate things and become the ghost in the machine. Best educational tool ever for kids.
