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