I P Conflict
Hi, After a power outage and reboot my duo is sending out 2 MAC address to the router which is causing a conflict. The router is an Asus RT- N56U and I am running the latest version of RAIDar. Any a...
Hello,
To answer your requests in order,
The router shows two entries for the NAS in the client status, both of them show the correct name of the NAS, when you hover the mouse over the first entry it shows the correct MAC address ie the same as the sticker on the rear of the unit starting 00:24:B2:xx:xx:xx
The second entry shows a completly different MAC Address starting D8:D4:3C:xx:xx:xx
I am recieving emails from the NAS stating
MAC address D8:D4:3C claims to have our IP address (192.168.x.xxx) (duplicate IP conflict likely)
RAIDar is stating that the MAC address is the one starting 00:24:B2
Hope this helps in looking for a resolution
Thanks for the details, greatly help understanding what's happening.
00:24:B2 is your ReadyNAS.
D8: D4:3C is NOT your ReadyNAS. It belongs to a Sony device.
The issue is not that two MAC addresses are sent by the ReadyNAS, the issue is simply that two devices have the same IP ("IP conflict", "duplicate IP"). The display on your router showing the same name for both occurrences of the IP is just because it able to distinguish the two.
The IP conflict is most likely due to one device using DHCP and the other being set to static IP on the same IP address, or both devices being statically set to the same IP address.
I'd advise you to set both devices to DHCP, if not all devices on your network to avoid any new occurrence of this, or to at least change the IP on one of these two for now.
Any idea what this Sony device is?
Hello,
Many thanks for your reply, the points you highlight were very informative. It would appear that the offending address belongs to my Sony Bluray player that is connected via ethernet to watch amazon prime videos, I have removed the cable from the player and there have been no further email notifications.
I have checked my router and was already set to hand out IP`s via DHCP so I don`t quite know why all of a sudden it has started to hand out two of the same adresses, if it comes to it I will ditch the Bluray and use an alternative.
I will mark this as resolved for the moment but may post back if it re-occurs.
Thanks for your help
Yes, but if your NAS is set to a static IP, then it will ignore the IP address handed out by your router and use what it is set for. That is the likely scenario and why that's not the best way to reserve addresses. The better method is to reserve the address within the router. If you cannot do that, then set the static address to somethng well out of the range likely to be assigned by the router, like xxx-xxx-xxx-200. If you change it, though, remember that anything else you set up that relies on the static address will also need an update.
Hello,
Thanks for the additional information, I have now reserved the IP address within the router for the NAS so hopefully that should be OK
