mac address conflict
I have started getting a message in my readynas duo logs which reads
mac address C8:2A:14:5B:72:EA claims to have our ip address 192.168.0.3 duplicate ip conflict likely,
it seems that it is conflicting because i,m having a job to connect to my nasduo
Any help would be appreciated.

- StephenBGuru - Experienced UserThe error means that you have two devices on your network trying to use IP address 192.168.0.3 (it is not a mac address conflict).
If you are using some (or all) statically/manually assigned IP addresses, then you likely accidentally created the conflict by assigning a duplicate address.
Assuming all your addresses are automatically assigned by DHCP - do any of your devices go into standby? If they go into standby for an extended period, than the router might be releasing/reusing one of the addresses. In any event, turning all your devices on and rebooting the router will cure this problem (at least temporarily).
You might also take a look at the DHCP lease times configured in the router. This should be longer than the normal standby periods you use. - bigboymalAspirantShould i apply ip addresses manually to eradicate the problem.
thanks for you reply

If you know which device is creating the problem, the quickest "fix" is to just reboot it. Restarting the router will also likely work.bigboymal wrote: Should i apply ip addresses manually to eradicate the problem.

You can of course switch to manual/static IP addresses, but if you don't know much about networks it might be best to continue to use DHCP. - I tend to find that with a NAS, static IP addresses are by far the best to use. You will easily find the procedures for doing this either in this forum or in the mac forums.

But with someone who has no understanding of DHCP, IP address structure, subnet masks, etc. it is probably better to stick with automatic assignment. If the router supports DHCP address reservation, that would be a very sensible middle-ground. - I still think its best to have a static IP address for the NAS, especially when using some of the Add-Ons etc. After all, To create a static IP address is hardly Rocket Science.
