Router – DNS Server address configured inside Router not working

dhcpdomain-name-systeminternal-dnsrouter

Well, I have an ISP router in which I have configured DNS Servers to use (Primary & Secondary) like Google DNS. It works just fine.

But now I have setup a computer with DNS server (Simple DNS Plus). I got it working by settings my internal DNS Server IP Address in computer. i.e. 192.168.1.3

So, instead of settings my internal DNS IP Address in every computer in my network, I want to setup DNS Server into my router. So on every DHCP request, computer get DNS Server to use.

So I configured it like this:

Primary DNS: 192.168.1.3
Secondry DNS: (left blank)

After applying and DNS Requests stop resolving. But strange part is DNS request does goes to DNS Server but maybe not returned back, because all DNS request were available in cache logs.

I don't know why this is not working, let me know if you have any solution or wordaround for this.

Thanks!

What's your Nslookup output? Have you setup your internal DNS server to forward requests it cant resolve to the router? Have you cleared your DNS resolver cache?

Edit

Login to the management interface of your modem/router and try to modify the Lan dhcp scope options for the dns server. if push comes to shove you can just connect your modem to your wireless router and control dhcp scope options (dns) from there. last case, manually assign your dns ip setting. this will work well for 1 or 2 pcs. anything over 5 will become a headache
