Why do I only like to use iptables in Linux?
Finally, it is for security considerations. Especially on Linux, using a third-party firewall always gives me a feeling of “letting a wolf into the house”. In addition, many third-party firewalls require payment. Compared with the free and open source iptables, I must choose iptables first.Of course, iptables is not all good. The lack of a graphical interface is a big shortcoming, which can be a big barrier for people who are not used to command line console terminals. However, Mingyue believes that as a qualified operation and maintenance personnel, it is still necessary to understand and be proficient in using iptables.
