IPs from the same subnet cannot be used on two different router’s interfaces. Use bridging in this situation (or routing if you prefer). You have to bridge wireless and ethernet interfaces both on MikroTik and other vendor routers. Keep on mind that station wireless interface couldn’t be bridged, that’s why please follow this example:
MT-CLIENT
Mode=station
proxy-arp enable in interface wireles and ethernet
WIRELESS: 192.168.1.126/25
ETHERNET: 192.168.1.129/25
Its very important mask network! and route default gw, (192.168.1.1 in wireless interface)
HOSTA=192.168.1.200/24
The problem of this configuration:
1º Only arrive at IP between: 192.168.1.0 - 192.168.1.127
2º PC ip the side client between: 192.168.1.128 - 192.168.1.255
AP-basic-Other vendor:
192.168.1.1/24
If somebody has some other configuration, post a reply!
