Is it possible to set up 2 subnets on the same interface in routeros without vlan?

Question

Mikrotik

Hello.
Initial situation
Several servers are rented in the cloud, united by a common vlan.
Access is through one of the ports of the provider's optical terminal, model ELTEX NTP-RG-1402G-W rev.C2
All vlan settings are made by the provider, for us everything looks like all servers are connected to one switch.
The organization uses mikrotik ccr1009-8g-1s, one of the ports of which is connected to this port of the optical terminal.
All servers in the cloud have an address space of 10.0.0.0/24
In the local network of the organization 192.168.0.0/24
Mikrotik has addresses 10.0.0.250 and 192.168.0.5, respectively, on 2 different interfaces
The gateway in the local network is separate, 192.168.0.1, on which the route 10.0.0.0/24 via 192.168.0.5 is simply registered.
In the network 10.0.0.0/24, the gateway is registered 10.0.0.250
Question:
There was a need to raise several servers in the cloud in the subnet 192.168.0.0/ 24
Is such a configuration possible without using vlan, considering that there is only one port for communication with remote servers on the optical terminal?
There is no task to separate subnets, on the contrary, it is necessary that access be from any to any.
Mikrotik has another free port.

Answer 1

I see no problem - assign at least a hundred IPs to the interface and prescribe the necessary routes. If you need several ports in one network, combine them into a bridge.
And yes, why the hell do you need 2 routers?
PS
In general, judging by the question, you clearly need a network administrator. The task of the level of a guy that the Internet pulls you home. Well, either I did not understand the task - sorry.
