Title: DNS Settings being ignored?
Post by: nofear_102 on October 13, 2013, 07:07:26 AM
Hi all, I am trying to force the use of a specific DNS server in conjunction with my local ISP which uses a dynamic IP system. I have done the following:
1. Set the primary and secondary DNS server addresses
2. Disabled "Enable DNS Relay"

The only way I can get the DNS sever settings to be acknowledged is if I set the WAN IP to static...since my IP is continaully being re-assigned this is not reasonable. I was using the same settings with my Linksys E4200 and had no issues what so ever (i.e. Dynamic ISP IP with primary and secondary DNS severs provided).

I have even tried leaving them blank and setting the DNS server information on my computer but it still fails.

Welcome! (http://forums.dlink.com/index.php?topic=41537.0)

Have you flushed the DNS cache from all devices after the DNS was set up on the router?

Internet Service Provider and Modem Configurations

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.

Here is the info...I tried the settings suggested below but no luck

Hardware = A1
Firmware  1.05b07
Region = Canada
Wired and Wireless

DNS Flush = Yes

ISP = MiMo
MTU is fine

Please let me know what else I can try...I have never had an issue like this in the past with other router brands.

ISP = MiMo  ???

MIMO technology is the same technology that cell phone providers are starting to deploy with the LTE networks. This technology allows us to stay future proof and ensure that we can always provide you the highest service possible

So I presume that there is some forum of modem or LAN cable connected to the WAN port of the 865L and that your getting a public IP address on the WAN side?

What are the DNS values seen under Status/Device Info/Wan section? Default should be your ISPs DNS. Now if you turn OFF DNS relay and input different DNS into Setup/Internet/Manual, does this change the DNS values seen under Status/Device Info/Wan section? It should...

Yes, there is an ethernet connection to the WAN port.  I have disabled DNS relay and input the primary and secondary DNS server settings to no avail...when I set a static IP everything works, the minute I go back to dynamic the DNS settings are ignored.

As mentioned, I have tested the exact same thing with other routers and there is no issue with dynamic IP and DNS.

The odd part is that in the status section it does show the DNS settings I provided (for dynamic and static).

Ok, I recommend that you phone this in and ask for level 2 or higher support from D-Link Canada. We use the same FW here however i haven't had a chance to test this on out on mine yet. Mines being used as a Bridge at the moment.

Please let us know how it goes and what they say. I hope they can figure it out...

O.k.

It's really weird, when I set a static IP the DNS settings I input are visible in my iPad, when I change to dynamic 2 additional DNS severs (from my ISP I am assuming) appear in addition to the 2 I input.

Yes, this model router is known for showing 4 DNS on query for some reason. I've mentioned this to D-Link a while back.
