Hi  @NovaSistemas  @MR.S 

 

Thank you for your feedback about this feature.

 

To understand this issue, would you please share us the following info:

1. Some screenshots showing the IDS/IPS DNS config ;

2. Does this only affect certain clients? If yes, what kind of clients are they?

3. How often will the disconnection issue happen?

4. The firmware version of the ER8411 and the controller you are using.

This is the current configuration.
Out of a total of 50 users, this has happened to many. I can't specify. All connected via Ethernet.
Disconnections occur several times a day.
The er8411 firmware version is 1.2.3 Build 20241121 Rel.21021
