Understanding the Foundations of IPTables and Linux Firewalls

An unexpected firewall outage is often less dramatic than its symptoms. A team deploys a new application and cannot reach it. One administrator sees an iptables rule that appears to allow TCP 443; another sees an nftables chain with a drop policy; the cloud security group also has its own restrictions. Before adding another broad… Read More »
