Hello,

i'm not sure if i really understand your environment. You have 2 routers (or more) and 1 server? What are the (static) addresses of the routers and which ip belongs to the server? The mentioned mac address belongs to which equipment? The server or one of the routers?

Kindly regards

Hi

Ip address conflict occurs when you have two different network devices(mac addresses) having the same IP address if you are using dhcp make sure the static addresses you have assigned is added to address reservation. if your IP range is from (i assume dhcp) .100 - .256 use static from the range of .10 to .100. (i understand thats what you have done too). Please check if any other device is geting these ip addresses ( statically configured)

Hi,

   If u r using DHCP please add the static IP's assigned to those devices in exclude list in DHCP server.
Try to find out the device with this MAC address 00:25:9C:8F:EF:99 and assign a static ip address (Dont forget to add it in dhcp exclude list.) . u can use arp -a command to get MAC-IP table. From that table u may get device ip of 00:25:9C:8F:EF:99.

Good luck

Set your server ipaddress to static address in a lower range, like 1-20, then make an exclusion to the dhcp scope to exclude 1-20.  That will prevent any conflicts.
