What tools are commonly used for port forwarding on Linux systems?

Common tools include iptables (native), rinetd (simple TCP forwarder), HTran (cross-platform), and EarthWorm (supports both forwarding and proxying). iptables requires enabling IP forwarding and adding DNAT/SNAT rules, while rinetd uses a configuration file.
