My request is about how to prepare Router Board 1100
To direct Internet addresses of the ports shown pictures
Data:
Gateway: 192.168.1.49./28
how to get 192.168.1.50 over ether2
This sounds more like a switching setup then a routing one.
In my experience the upstream provider will assign you a /30 for your internet side and route an additional /28 to your router where then you can break it up as needed. Sounds like you need to just set it up as a switch and assign static IP’s to your devices.
