Each Pi is connected to wireless (192.168.1.0/24) and they share an internal, wired, 10.248.0.0/16 network.</p> <h2 id="virtual-ip">Virtual IP</h2> <p>I want one IP address to be load balanced across the three Pis. This can be with the <a href="http://security.maruhn.com/iptables-tutorial/x8906.html">CLUSTERIP</a> target in <code>iptables</code>. In <a href="http://www.raspbian.org/">raspbian</a> the kernel module for this was not enabled, but luckily this was <a href="https://github.com/raspberrypi/linux/issues/812">fixed</a> very quickly.</p>
