A shell script that sets up iptables port forwarding rules on Linux servers, with automatic rule updates when a DDNS domain's resolved IP changes. It provides an interactive menu to add, delete, and list forwarding rules and runs as a systemd service.

Use cases

• forward ports through a relay server using iptables
• set up port forwarding for a ddns domain that auto-updates on IP change
• list and manage iptables nat forwarding rules interactively
• relay traffic to a trojan server behind a changing IP
• back up and restore dnat forwarding configurations

When to choose

• you need simple interactive port forwarding on a Linux box with iptables
• your target host uses a DDNS domain and rules must follow IP changes
• you want a lightweight shell-based NAT relay without extra dependencies

When to avoid

• you need Docker-compatible or port-range forwarding - the author recommends nftables-nat-rust instead
• you run nftables-only systems without iptables support
• you need a maintained GUI or non-interactive configuration management
