dd-wrt has built-in support for a whole list of Dynamic DNS services. Unfortunately, they only support HTTP-based services. I use a standard RFC2136 DNS update. Here’s how to add nsupdate support to dd-wrt.

Although the big builds of dd-wrt contain IPv6 support, it doesn’t support ip6tables. Hence, I choose to use the mini build (which gives me the most free space) and add the missing parts myself. I shamelessly used OpenWRT modules to save me the trouble of figuring out how to compile each library. (Unfortunately, my router isn’t supported by OpenWRT, so I need to stay with dd-wrt for the base system).

Since none of the dd-wrt releases include ip6tables support, I added it myself. The standard kernel does support module loading, so you can simply add additional kernel features without reflashing the device. You do need some writable storage. I use the remaining 4MB of flash using JFFS, but using an external storage (USB, network, …) is also possible.
Since you can’t run a complete build environment on the router itself, you’ll have to set up a cross-compiling environment on your own machine. As I found out, this isn’t always very easy to do…
