ARP POISONING

RouterOS General
1

Hi,
I got two mikrotik RouterOS V4.5.

My setup is such like:

Router A: Public interface:202.153.65.128
Local Interface:192.168.80.1/24

Router B: Public interface:202.153.65.163
Local Interface:172.24.12.1/24

Both of the local interfaces are placed on a same switch with default vlan1 and
interfaces are in ARP enabled mode.

I am facing arp poisoning problem
Both routers local interface’s mac are flooded on the either side.
No one is able to get internet.
How to block the MAC flooding through the local interfaces.

if they are both on the same switch there is nothing you can do - except vlan them from each other. thats like filling a bucket of water with two hoses and wanting to keep them separate.
