How to set up a bridge port with WAN on Mikrotik LAN to forward the second IP to the server?

Question

Computer networks

There is mikrotik rb750gr3. Out of the box RouterOS 6.42.7
WAN as ether1, the rest of the ports are in the default bridge. Nat is working. All out of the box.
It is necessary for the server on the ether2 port to bypass the sikrotik to be in the provider's network. From a DHCP provider, get an IP, that is, isolate the port and configure it stupidly as a switch with a wan port.
How to do it? I searched for three days and did not find it.
PS master port->slave port in this device is cut out.

Answer 1

You make a bridge of two ports, turn on the provider in the first, and the server in the second. Or you raise several addresses on the provider's interface, and then do NAT 1: 1 for the required address towards the server.
