## What it is
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
