Odd MAC to no where

PeterUK

V1.30(ABWV.1)ITS-24WK47-m6271

So its fixed now but was really odd

I had a VLAN47 with a reserved IP 192.168.255.41 to MAC VMtestPC the VMtestPC get the IP does the ARP to the gateway 192.168.255.39 send a ping but then the gateway send the reply to this known to me MAC Microsoft_f8:a1:0a (00:15:5d:f8:a1:0a) even if I ARP the subnet with VMtestPC off I see reply by ARP scan for that IP I unreserved the IP and unplug the Ethernet and back and it did not fix it pinged 192.168.255.41 from FLEX and FLEX did not ARP the IP just pinged to the MAC but disable/enable VLAN47 interface fixed it.

Hi @PeterUK

If you experience the same behaviour again, we recommend preserving the environment as it is and providing us with the following information via private message to help us better understand and analyse the situation:

• Enable HTTPS WAN access on your firewall for remote troubleshooting.
• Capture the packets for the relevant interface to observe the traffic flow.

Your assistance in gathering this information would be greatly appreciated.
