void store_all_firewall_rules(firewall_rule_t *rule_head);
void store_firewall_rule(firewall_rule_t *rule_ptr);
\end{lstlisting}
\subsection{Space Allocation}
Each rule will get exactly the space it needs (\verb|firewall_rule_t|). Therefore a maximum of rules of \textbf{15} is specified in the constructor of the class. At the lowest storage space, there will be 8 bit for the current amount of rules to keep track how many rules need to be restored at power up.
