dhcp server and network help on RB850Gx2

Hi all,

I am pretty new to RouterOS. I want to have implement a few things but had hard time. So I wanted to have your ideas and implementation solution. Please see attachment.

What I want is:

  1. The interface with PoE needs to have its IP from ISP (dhcp client)
  2. “Device that needs IP” needs IP from local DHCP server. That device will change, so every new device that will connect to port 2 should have a different IP (which come from DHCP server I guess ? )
  3. Host’s IP remains as is. It needs just one time IP that could be dynamic or static (which might be given by DHCP ?) . Any ideas here ? Which one would be suitable and how ?
  4. Only host can communicate with ISP. So there would be a forwarding ? “Device that needs IP” may not connect to ISP directly.
  5. Host and “device that needs IP” can connect to each other. So “device that needs IP” can only connect to ISP over host.

What kind of topology should I follow ? Any help is appreciated.

No help needed anymore. I simplified the template, it worked. Thanks for reading.
