How to Forward Ports With Iptables in Linux?
Port forwarding is a technique that allows external devices to access services running on internal network devices by redirecting traffic through specific ports. When you want to run a web server from your home computer, external users need to connect through your public IP address via port 80 (HTTP) or port 443 (HTTPS). Without proper port forwarding configuration, incoming connection requests are blocked by your router's firewall, preventing access to internal services. Iptables is a powerful Linux firewall utility that operates at the kernel level, providing robust packet filtering, NAT (Network Address Translation), and connection tracking capabilities. It can ...
