Hello,
I have a server with 2 eth port. The port 1 IP is: 10.0.13.2, port 2 is: 192.168.11.2. I have two network card in the server, with diferent MAC-s. But in microtics ARP list the diferent IP-s has same MAC address.
Is that a BUG? What can I do with this? Now one of this networks is unreachable.

Thanks for the help!
Hi,
I think ROS is innocent here. I don’t know how is the server connected to the routerboard but proably you should check your server settings. The default values for some IP stack features IMHO can cause what you see. I think you should try to check/change values for arp_filter and arp_announce (accessible under /proc/sys/net/ipv4/)
Use tcpdump to see what your server announces in ARP queries/replies.
Hello,
Thank you for the idea. I made a bridge the 2 eth in the server. It is solved my problem.
