What will I learn?
The Linux Iptables Course equips you with hands-on skills to create, set up, and fix secure firewall rules on gateways with multiple network interfaces. You'll explore iptables structure, chains, tables, NAT, and stateful filtering, then develop straightforward, sustainable rules for local area network, demilitarised zone, and internet traffic. The course includes logging, monitoring, secure rollout, and checking to help you reliably safeguard and adjust actual setups.
