Good time of day! Such a situation, using a script to changeip.com http://wiki.mikrotik.com/wiki/Dynamic_D ... angeIP.com
The script should be updated only when the interface is changing ip. This is not the case at the first performance of the script, it performs the upgrade, but the next time you update it will update, hatya should not. And if the script immediately after the first run, it works, ie does not update as compared to the variable $ ddnslastip. Ie the impression that the version 3.27 does not hold the variables for more than 20 seconds. Who can recommend something?
