Router settings for same IP range at each port

RouterOS Beginner Basics

Hi all,

I am looking for a networking solution to use in a testing / production environment. We create PCB with an ethernet interface. All PCBs have the same default IP address (192.168.1.1). Each PCB has to pass a functional test before it is sent to our customers. This functional test includes powering up the PCBs and communicate via its ethernet port with a testPC.

The testPC is now connected to one PCB, so only one PCB can be tested at the time. I want to test 4 PCBs concurrently, connecting each one to a port of a MikroTik Hex. Then I want a seperate subnet for each PCB at the testPC side.
192.168.1.x on the testpc goes to port1 192.168.1.x;
192.168.2.x on the testpc goes to port2 192.168.1.x;
192.168.3.x on the testpc goes to port3 192.168.1.x;
192.168.4.x on the testpc goes to port4 192.168.1.x;

I think I can set up the routing for each subnet to ist specific port with the “IP” → “Routes” settings.
But how do I translate the different testpc subnets (192.168.1.x; 192.168.2.x; 192.168.3.x; 192.168.4.x) each to the same subnet (192.168.1.x)?
I think I need NAT - network address translation, but I cant find it in the router settings.

Thanks in advance,
Stef

There is no need to use different subnets.Just give different address to every PCB, for example 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5.

Hi Zacharias, that would be a solution, but to set another IP address in the PCB we first have to make connection via its ethernet interface on its default IP, reboot and after the test reload the default IP like noted in the PCBs documentation. If we can work around this, we can save a lot of expensive production time.
