A firewall's complexity is known to increase with the size of its rule set. Empirical studies show that as the rule set grows larger, the number of configuration errors on a firewall increases sharply, while the performance of the firewall degrades. When designing a security-sensitive network, it is critical to construct the network topology and its routing structure carefully in order to reduce the multi-firewall rule sets, which helps lower the chance of security loopholes and prevent performance bottleneck.
