HOWTO: Linux NAT in Four Steps using iptables. By Frank Wiles In everyone's life a little rain must fall.
My main Linux workstation at home suffered a hard drive failure the day after Christmas. I can only guess I was bad last year and Santa turned my hard drive into a lump of coal as punishment.

Monitoring. Home networking. Bluetooth. Making NetworkManager work with suspend/resume. Dnsmasq - a DNS forwarder for NAT firewalls. Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot.
It is designed to be lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It has also been widely used for tethering on smartphones and portable hotspots, and to support virtual networking in virtualisation frameworks. Supported platforms include Linux (with glibc and uclibc), Android, *BSD, and Mac OS X.
Dnsmasq is included in most Linux distributions and the ports systems of FreeBSD, OpenBSD and NetBSD.
