What's next?

What's next?

This chapter has discussed how the state machine in netfilter works and how it keeps state of different connections. The chapter has also discussed how it is represented toward you, the end user and what you can do to alter its behavior, as well as different protocols that are more complex to do connection tracking on, and how the different conntrack helpers come into the picture.

The next chapter will discuss how to save and restore rulesets using the iptables-save and iptables-restore programs distributed with the iptables applications. This has both pros and cons, and the chapter will discuss it in detail.
