Problem with DNS update script on 2.9.51

RouterOS Scripting
1

Hi, i am trying to connect to a PPTP server that does not have a static IP address so on my Mikrotik 2.9.27 router i have scheduled the following script:

:global vpn-interface-name "pptp-out" 
:global vpn-dns-name "dyndns.no-ip.biz" 
:global new-vpn-ip [:resolve $vpn-dns-name] 
:global current-vpn-ip [/interface pptp-client get $vpn-interface-name connect-to] 
:if ($current-vpn-ip != $new-vpn-ip) do={/interface pptp-client set [find name=$vpn-interface-name] connect-to=$new-vpn-ip}

It works perfectly, i must admit, but when i tried to set the same thing on a 2.9.51 router it didn’t work.
Even though the scheduler runs the script (i can see that from the run count of the script list) the IP address is not being updated at all. I have had a lot of tries but still can’t make it work.

Is there any problem with the syntax or something else? :unamused: :unamused: :unamused:

Thanks in advance

Do you have primary and secondary DNS server specified in your MT?

From CLI can you resolve domains?

The DNS servers are set correctly and i have managed to resolve domains from command line successfuly. It’s not that :frowning:

It resolves on my 2.9.51 to 69.65.19.125.

Is this correct?

I’ve just used this script to connect to a Draytek 2910 using PPTP from a RB532 running 2.9.51

Works fine.

So it’s not your script :slight_smile:
