Updating Google Domains from DD-WRT

I have had a Netgear WNDR3700v2 router for a few years already and I bought this model specifically because I could flash it with the open-source DD-WRT firmware. The reasons remain the same as the ones I had in 2006—the key ones being: the ability to run a Dnsmasq DNS/DHCP server for my local network; and the ability to update a single Dynamic DNS address so that I can access my home network when I’m on the go.

Trying out DD-WRT

Past Christmas I bought a Linksys WRT54GSv4 router to improve wireless access to my home network. Of course, I’d have bought an access point, but I also wanted to replace most of my home server/router functionality with this little device so that I could eventually remove the server box. Therefore it had to provide: NAT. Firewalling. Port redirection. A dynamic DHCP server. Ability to configure DHCP static entries (used for servers within the network). A local DNS server to resolve names for local machines. The first four items were all provided by the official firmware but unfortunately not the last two. However, if I chose that specific model was because it could easily be flashed using OpenWRT or DD-WRT, both of which allow to set up those services by using, e.g. Dnsmasq.
