One Router, Two separate networks/internet connections

Hello,

I currently have one internet PPPoE line and planning to get an extra line with a fixed IP and a routed subnet.
My small rack can barely fit an extra router so I was thinking to use my current RB1100AHx4 Dude for both internet lines.
Connection 1 will be a fixed public IP with a routed subnet behind it. 1 Gbps symmetrical. This will be used for a VM Supermicro server without NAT.
Connection 2 is a PPPoE with dynamic IP. 1 Gbps download and 500 Mbps upload. This will be used only for a local network with computers, laptops, etc behind NAT.
I want both connections to be logically separated. No fail-over or aggregation.
Anyone uses such a setup maybe with a RB1100AHx4 or somewhere around its performance and can tell me if the router can handle it?

Thank you.

Based on the test results, it should do just fine: https://mikrotik.com/product/RB1100Dx4#fndtn-testresults
But it will always depend on the config applied…
