Block anydesk entry ports

NethServer Version: NethServer release 7.9.2009
Module: Firewall


I created the rule blocking red to green traffic but it doesn’t seem to work.

I did the same procedure blocking teamviewer but with the latter it effectively blocked everything and the rule works correctly.

the only difference is that teamviewer was already present among the services with a small customized icon in the shape of a monitor.

instead anydesk I had to create a rule through the firewall module blocking the following ports: 50001–50003 and 6568, this rule is represented with small gears.

Where am I doing wrong ?
