Dynamic IP -> Router -> Update Open DNS

March 22, 2017 18:43

Requirement:

Update multiple Open DNS Networks with dynamic IPs using the routers dynamic DNS updator. (A Windows application is not a viable option for these networks)

Confusion on my part:

After reading multiple threads on here I'm confused what the best solution and how to configure it. Dyn, Dnsomatic or OpenDNS direct???

DNSomatic seems to be linked with OpenDNS as using the same email and password for both sites enable my Networks to appear from OpenDNS in Dnsomatic? Magic?

Equipment

I'm restricted on the 4g routers for these dynamic IP networks Teltonika 950. (I get a Public routable IP from the ISP)

Questions

So after reading threads on here Im guessing Rotblitz might be answering this.

- I dont need to update any other services of the IP address other than OpenDNS is there a need for DNS OMatic in this senario?

-Looks like my router may not support https (havent tested yet) for updates to OpenDNS. Is this a reason to use DNS OMatic?

-What are the default fields I should be looking to fill in?

Any ideas what i would use to connect with this Draytek?

"as even the simple http url didnt work."

My router with an earlier firmware didn't want the protocol in front of the URL, so try without:
```
updates.opendns.com/...
updates.dnsomatic.com/...
```
Later on, with newer firmware, I can also use the protocol, i.e. HTTP or HTTPS, because HTTPS is supported now.

Generally, you may need to play with many variations. Your best bet is to visit a forum where your router is being discussed. There are usually the router nerds who can help.

Yeah all networks will need different IPs so agreed will need to add the network label, however just updating an IP for any network will be a start.

The router is quite niche, I havent found a forum yet for them (well in English).

Will keep plodding on with different setups.

BTW thanks for the help so far!!!

Hi,

Did you have any luck? I'm even totally lost how to get my rut955 to "connect" to opendns.

Can you post a link to an online user manual of your router?

Provides all downloads.

Might give an idea what is required. I had opendns running smoothly on a tplink using primary and secondary IP address options but this one I just can't figure out.

The configuration can consist of two things:
- Configuring the OpenDNS resolver addresses 208.67.222.222 and 208.67.220.220 to direct all DNS traffic to OpenDNS. Your user manual is not such specific to show if this is possible on the WAN side or the LAN side. However, their Wiki https://wiki.teltonika.lt/index.php?title=WAN seems to indicate that you can "use custom DNS servers".
- Updating your OpenDNS dashboard with your current dynamic IP address. This should be possible with the DNS-O-Matic option in the Dynamic DNS section of the router.

I've been able to set up noip.com which is a fun thing to have but still cant get opendns to work.

Again, this is the step to start using OpenDNS (most important):

Enter 208.67.222.222 and 208.67.220.220 into the yellow marked fields.
Then test at http://welcome.opendns.com/ if you're using OpenDNS now.

Regarding the IP updates:
Configuring noip.com is nonsense. As I said, you configure dnsomatic.com. Before you do this, visit DNS-O-Matic to set up OpenDNS as service.
This exercise is to keep your IP address information automatically updated at https://dashboard.opendns.com/settings/
UnIike the first step, it is not to use OpenDNS, but to use your customized dashboard settings.
