Until recently, I was using DHCP combined with the IP-MAC Bidding/ARP inspection feature. However, when I detected a conflict that didn't exist before, I found out that the ER605 V2 is not capable of working simultaneously with DHCP and IP-MAC Bidding.

I always worked with it this way, detecting these conflicts and packet drops, but it never affected my access.

Since today I noticed many warnings coming from a smartphone, I became suspicious, but in the end I discovered that it's a feature of smartphones that constantly changes the MAC address, causing the conflict problem. But I'm curious, what I did isn't wrong. However, the ER605 V2 doesn't seem to have the capacity to support dual identity authority.

I wanted to confirm this and what products could replace it.

"This MAC address conflicts with an existing DHCP Reservation entry." <--
