Hi there. I’m trying to achieve the following:
I want to have my mikrotik eth1 port as WAN port and all the other ports of mikrotik in one bridge with DHCP enabled and network 192.168.1.0/24. Now if my modem (connected to eth1) is in different network all working good, modem gives DHCP to mikrotiks eth1 and use this as gateway for the bridge network BUT how to do this even if my modem is in the same network 192.168.1.0/24?
Re: Eth1 as WAN port with DHCP regardless IP
The modem should provide a public IP to your router and in this case there is no issue with whatever subnet you choose for your LAN.
However if the modem is NOT giving you a public IP but a private IP address, then you have to make sure that your LAN is no a different private SUBNET>

Re: Eth1 as WAN port with DHCP regardless IP
If I paraphrase what @anav wrote: router can not have two interfaces (between which it sould route traffic) with same network address.
Usually one doesn't have much influence on what IP address comes on WAN side of SOHO router, hence one has to adjust LAN side in case of conflicts.

You have to change the IP scope on the MODEM (You probably mean gateway, aka it has a router in it)Hi there. I’m trying to achieve the following:

OR
You have to change the IP scope of the Mikrotik
ip scope
192.168.1.0/24 is an IP scope
Changing your router to 192.168.254.0/24 scope... would take care of this.
