Working on 6.46.2.
Thanks.

Good morning. Today you have been able to use this script.? try to use it and don't update the ip the no-ip dashboard, note that I am behind a balancer.

The router and my no-ip account hasn't been used in almost a year, sorry.
Only ever used it on my (very simple) home network.

Working on version 6.49.6
Thanks

GRACIAS
