Emulate/simulate forwarding ip address on an interface

RouterOS Beginner Basics
1

Hi!

I am looking for a solution to the problem of testing some specific configuration where I use forwarding on a WAN interface. There is an option I can put an extra router with an IP address on this interface but → is there any other solution to emulate a forwarding IP address? I know how to create a loopback-bridge and add IP address to it but it will become another incoming (local) interface so no mangle forward rules will be involved - moreover it will also add an extra preferred source to this network so may change packet flow.

Do you know how to handle this?

You could try something like this:

But another router is much safer, because this can easily go wrong and interfere with regular config too much.

Thank you, Sob.

It seems to be quite complicated and can potentially influence my problem (mangle rules testing). Are there any other options which come up to your mind?

If I want to test something with mikrotik I use Virtulbox or Eve-NG (https://www.eve-ng.net/), for simulating.
If I want have to test something on teal hardware, I rot the traffic to a PC or a VM, without the service (blocked by PC firewall / monitored wireshark, whats needed).
A other option is to set up a ip-address on a switch and put some firewalls rules on it.
The best was, I think, is to use a VM with RouterOS, so you can isolate the traffic and monitor it.

Good point, @afuchs.

Is there any way to achieve it directly on ROS or no easy way?
