Can't use my domain name

The domain name I have is ‘’ the router won’t allow the .net what I get is

Why the limitation? I can’t use your router. HELP

See page 31 and 35 of the manual for information on how to configure the Dynamic DNS (DDNS). 


doesn’t solve my problem. I can’t use the domain that I’m on. My linksys handled my dns including allowing my domain name but I wanted to try the wd. I don’t care about the outside world. I don’t want them connecting to my machines. I care about my internal network. I have to manually change my domain name every time I reboot a device. This is very inconvenient to say the least. I’m ready to return this and get another linksys.
