Model: ER707-M2  
Hardware Version: V1
Firmware Version: 1.2.3

Currently the IP-MAC-Binding feature is not working for me. The bindings no longer show up in the arp table of my router. 

Context
Im running the Omada SDN Controller: 5.15.24.21 on a OC200 together with a router ER707-M2 V1.2 Firmware 1.2.3.

Situation
I have setup a IP-MAC-Binding in the controller like this and made sure the enabled checkbox is turned on

 

 

If the PC is on, I can see the arp item as below with type 2 mark

 

After a few seconds the computer is shutdown the entry disappear from the arp list, as below

 

 

I'm using this feature to send a Wake-on-Lan from the internet. If the computer was shut down a few seconds ago everything works, but after a couple seconds the entry disappear from arp and a can't turn the pc on anymore

 

Tried to reboot, force provisioning on the router. Delete and recreate the entry, but always I get the same behavior. Looks like a bug to set the entry permanently on arp table

Hi  @lemaoCool 

 

 

Please have a look on the following guide to see if you missed any config:

 

How to configure WOL (Wake On LAN) on TP-Link SafeStream Router using the new GUI

 

 

Especially Step 3 Configure Virtual Server

 

 

The guide is under standalone mode, but the steps are the same under controller mode.

Hi  @Vincent-TP 

 

Yes, I did follow all the step in the guide. The screen of the virtual server is below

 

 

As I mentioned, as long as the entry appears on the arp table through terminal, The WOL woks perfect. After a couple time, when the entry is removed. It stops working. The problem seen to been that the arp entry is not persisted.

Tried with the er605 in the same controller version and OC200 and the same behavior Happen.

Thanks for the feedback.
