ATP500 Arp Spoofing detection

Dear all,

We are preparing the fixed firmware now, once there is further update and will update it here. Currently, we confirm this symptom doesn't have further service impact, it should be a display issue. Thanks for your understanding and patience in advance.

@zyxel_jeff and @Zyxel_Jerry only ZLD 5.xx firmwares are affected?
This issue will lead to WK/Lab Firmware or an official release?

Hi @mMontana

We noticed this issue occurs on V5.35 firmware and we plan to release WK firmware to fix it within the next two weeks.

Seeing this too on VPN300 and FLEX200

The issue seems to happen then the USG sends a broadcast ARP to a IP.

Here the same problem with USG Flex 200 with firmware V5.35.

Dear all users,

Please refer to the V5.35 WK06 firmware, this firmware already fixed the issue that there are many IP conflicts messages on the Monitor log. Thanks
