Static DNS not working

I have a server that obtains a static IP address from the router (192.168.1.30), and have set up a static DNS to match (MediaVault). However, when I perform an 'nslookup', the router doesn't find the address in its table, and returns
Code: Select all
C:\Users\Nevans>nslookup MediaVault
Server: Billion_Router.home.gateway
Address: 192.168.1.254
*** Billion_Router.home.gateway can't find MediaVault: Non-existent domain
[code]
If I do a reverse lookup, the correct host-name is returned.
Unless I'm going mad, this did work when I first set it up, but stopped today. Having tried everything I could think of, I re-installed 2.32d, and did a factory reset, and then re-loaded the original config, all to no avail. What have I done ?

Have you tried to disable the DNS proxy?? under 'Advanced Setup >> DNS Proxy'

Hi Billion_Fan,
Just tried that, but now the router is passing BT's DNS servers to the clients.
Code: Select all
C:\Users\nev>nslookup mediavault
Server: indnsc101.bt.net
Address: 213.120.234.34
Non-authoritative answer:
Name: mediavault.home.gateway
Address: 92.242.132.15

Have you tried to set your DNS server to the WAN profile?

Hi Billion_fan, not sure what you mean by this. In the DNS settings, ppp1.1 is the gateway for DNS traffic, with USB as the secondary.

Hi Billion_fan, I think that I've confused you. It's not a static DNS server entry that I am questioning, it's a static DNS entry in the routers DNS table.

If you take the router out of equation, and set a PC with a satic DNS sever pointing to the DNS server, is there any issue?

I've solved it! I telnet'd into the router, and looked at the 'Hosts' table, and discovered that all DHCP derived entries had two entries. One was just the hostname, and the other was the FQDN i.e. hostname.home.gateway. I added two entries to the static DNS table (Advanced -> DNS -> Static DNS), and now MediaVault is resolved correctly.
Code: Select all
C:\Users\Nevans>nslookup MediaVault
Server: Billion_Router.home.gateway
Address: 192.168.1.254
Non-authoritative answer:
Name: MediaVault.home.gateway
Address: 192.168.1.30
and this is what I configured on the router:
