Dynamic DNS services allow people with a dynamic IP address from there ISP (like me) to access resources using a name instead of by IP address. Most routers have support for updating dynamic DNS services, but are usually limited to one service. I use DynDNS (free, which is no longer offered) for this type of access. I wanted to switch my DNS servers to OpenDNS and while they don’t require the same type of updates like DynDNS to work, they offer some interesting features like stats and category filtering using a dynamic DNS type service. The problem is my router only support updates for one dynamic DNS service and it was already updating DynDNS. Luckily, OpenDNS also runs a service called DNS-o-Matic which will update multiple dynamic services at once. Here are some quick steps to set this up on DD-WRT.
I upgraded my Linksys WRT54GL with the DD-WRT firmware a while ago and used it as a wireless bridge for internet access in my bedroom where there aren’t any ports (yet). I was using an old D-Link wireless router as the main router, but wanted the upgrade in functionality that DD-WRT provided. So I reset it back to “Factory” default and set it up as my main wireless router. This is mostly for my reference if needed later, but if it helps anyone who happens to stumble upon it later than even better. Continue reading My DD-WRT setup
