DDNS Setup Teltonika 950

[hehs]

I am trying to use the following post to setup DDNS under VIP on Teltonika RUT950 but am not having any luck. For reference I have whitelisted 2 sites in the VIP account. The router is 4G WAN with an ISP provided dynamic IP.

I have setup up custom DNS as follows which correctly filters according to the family level

I then try the following in the DDNS settings, including many combinations thereof, ie lookup host with/without host name, hostname empty/with my OpenDNS label, address source as public/private, http secure on/off all to no avail ie status is always NA and whitelist filtering only occurs if I update the IP manually via OpenDNS web interface. Unfortunately whilst there are suggestions in the post linked above there aren't any final results form the original poster.

For reference the DDNS field descriptions for the router are as follows.

Appreciate any ideas here.

What you entered into the lookup host field is not an FQDN, but an update URL. You need to enter a hostname (FQDN) which has the WAN IP address of your router assigned, i.e. where an nslookup would show your router’s WAN IP address. Strictly do what the description requires you to do. If you don’t have such a hostname, then you may need a DDNS service in addition. You could also try to use myip.opendns.com as lookup host which has your IP address assigned.

Then look into your router log to see what it says about the DDNS updates.

Else you may try with DNS-O-Matic as described in the other thread. But also there you need a hostname.

Further, in "URL to detect" you better do not use Dyn's/Oracle's host if not using a DDNS service of them.  The appropriate URL would be http://myip.dnsomatic.com/ or http://diagnostic.opendns.com/myip which both belong to Cisco/OpenDNS.
