LAN IP conflict on Vigor 2766 was created by xer0w
Hi,

Since upgrading to the latest FW (4.4.5.5_BT) on my Vigor 2766, I keep getting the following ARP messages logged for any Windows device that connects to the network (LAN or WIFI): (Android devices don't generate this message)
Code:
vigor2766 DrayTek: [ARP][LAN IP conflict - lan ip conflicts with the one host whose MAC is xx:xx:xx:xx:xx:xx, please contact with the administrator]

There are no IP conflicts on my network, I've checked both on the devices in question and performed an ARP scan using other tooling, and everything is working as expected. Perhaps a bug with this FW?

A quick update on this. I logged a call with DrayTek support and provided the log, initially they suggested it might be a conflict with the WAN address, which didn't make any sense.
So I checked my logs from the previous FW version (I archive them via Syslog) and confirmed that these log entries do not exist.
They've now replied saying "we're not sure what is causing the issue" and to stick with this FW.
