Using a DLink 2640-T (ADSL2+Router). It cant resolve the internal hostnames. The manual is pointing to the firewall settings of the router to switch off the DNS-Blocking from external (which doesnt make sense to me). But even with that in place it just does not work. And all I got from DLink support: Please reset and try again… What I did, no change.
Thanks for any advice

I seriously doubt that the D-LINK 2640-T has a built-in DDNS server. According to the Datasheet on that product it has DNS Relay support, and DDNS. The DDNS functionality is implemented as a DDNS client to update public DDNS sites so that your External IP of the DSL Router can automatically update DNS records on the Internet. I doubt they include a DDNS server that allows your "internal" clients to self-register with teh DSL modem/router device.
The DNS relay portion is to permit your "internal" clinets to point to the DSL router/modem and have it forward queries recursively to the Internet for resolution.
You will need to either use hosts files or run your own Internal DNS server.
