How to reach a interface port from LAN / WAN on Mikrotik Router

Good morning, i’m Denis!

I have a question that I can’t get out of and I can’t figure out how to do it:

Basically, on “interfaces”, on the “eth2” port I connected this DHCP device, an xDSL modem, which is in bridge mode (not router - the VLAN and PPP are managed by Mikrotik). My request is this: how can I reach the web interface of this modem / of any device that is connected on “interfaces”?

Given that, this ETH2 is a WAN interface, a backup connection, the ETH2 port is not part of the bridge. And above all, how do I have to do so that I can assign an IP to this modem, even if it is in DHCP, to then reach it?

One last thing: how do I create the routing rule? Where do I have to act exactly and how do I compose the rule? My request is to reach this modem (or any other device it is) from the internet (but even from a local network is fine for me), how do I do it?

I hope I made myself clear. Thank you for your time.

Try adding a DHCP client to the Ethernet interface, not the PPPoE one, with add-default-route turned off (if under “DHCP device” you understand a DHCP server):

/ip dhcp-client
add add-default-route=no interface=ether2

For access to it from the internet, add a dstnat-rule pointing to it
