ip46nat User's Guide

About this manual

The ip46nat project implements IPv4‑to‑IPv6 NAT, allowing IPv4 traffic to be forwarded over IPv6 networks. Two migration modes are supported: direct IPv4‑to‑IPv6 NAT and PPP/L2TP over IPv6. The guide covers the status of the project, required software components, and the steps needed to install the modified Linux kernel and the ip46nat kernel module on supported LinkSys devices.

Installation steps include connecting to the router, performing a firmware upgrade via the original web interface or the Linux console, installing required ipk packages, and loading the ip46nat kernel module. Network configuration commands for enabling forwarding and setting up routing are provided, followed by details on how the NAT module translates packets in both directions.

Frequently asked questions

How do I upgrade the router firmware using the original web interface?

Open the router’s web interface (e.g., http://192.168.1.1/Upgrade.asp), select a firmware file that ends with -squashfs.bin, and click the Upgrade button. Do not interrupt the process.
