on eth2 have my local network 10.0.0.200 conected to a switch
thats work fine

now a have a power user with ip 100.100.100.61 255.255.25.248 and i need to conect it to eth3 on my mikrotik

my cuestion is how i have to configure my eth3 and router ?

thanks jose

  1. Configure proxy-arp on ether1 and ether3 interfaces
 /interface ether set ether1 arp=proxy-arp
 /interface ether set ether3 arp=proxy-arp
  1. add a static route for 100.100.100.61
/ip route add dst-address=100.100.100.61 gateway=ether3 distance=1
  1. Configure the power user system as follows:
    IP Address: 100.100.100.61
    subnet mask: 255.255.255.255
    Gateway: 100.100.100.62

Be sure to exclude 100.100.100.61 from your srcnat masquerade rule.

on eth1 i have 100.100.100.61 with arp-proxy but ?

what ip address i have to put on eth3?

Remove IP 100.100.100.61 from your router completely. 100.100.100.61 should be assigned to the user.

You don’t have to assign any IP address on eth3.

ok i going to try
