DNS Configuration - NVG510

I, unfortunately, was recently talked into "upgrading" my DSL to U-verse - so I could save 5 dollars a month. I have encountered an issue with the NVG510. Try as I might, I am simply unable to envision a situation where it would be beneficial to lock down the DNS configuration so that a person is unable to change it. What is the purpose of it? Is there a way to "unlock" this so you can manually change your DNS servers without having to bridge another router? Had I known this was going to happen I would have just stuck with my old DSL - it was half the speed that it is now but at least it was functional.

Unfortunately, DNS settings are hard-coded in all U-Verse routers, because some U-Verse services (VOIP and IPTV) use DNS names that only the AT&T DNS servers can resolve.

To use your own DNS settings, you can use your own router behind the NVG510, or you can make individual DNS entries on each device.

The problem with "solutions" such as changing to the desired DNS servers on your devices or using your own router behind ATT won't help resolve speed because the slow ATT DNS are #1 and #2 and your local DNS will be #3 and #4 in the order of query.

You might checkout DNSBENCH.EXE by Steve Gibson for more details. See below.

The ATT DNS servers are so horrendously slow that I/m considering dumping ATT Uverse and if ATT won't let me switch back to DSL then I'll dump them altogether.
