I have one Mikrotik RouterBoard RB450G.
My requirement is configuring one port for WAN and other ports for LAN.
I configure the second port for LAN with IP: 192.168.168.1/24.
When I start using it, I can not connect to the third port to get IP: 192.168.168.0/24 the same as the second port.
I mean I want to configure one port for WAN and other 4 ports for LAN look like other Wireles Routers with one built-in port as WAN and others for LAN.
