How best to set up Mikrotik in front of the server and is it necessary?

Question

Mikrotik

There is a Proxmox server on it with 4 containers and one virtual machine, the provider gives 4 ip addresses for each container, and we wanted to connect to the virtual machine via VPN (asterisk is spinning there).
The cable from the provider is connected to Mikrotik, which in turn is connected to 2 network ports and one IPMI.
How to configure it is better to configure Mikrotik so that it passes traffic to all 4 addresses to the server?
Or is Mikrotik not needed at all? Just buy a separate IP for the asterisk and that's it.

Answer 1

They put on the perimeter what they are sure of and know better, plus the possible requirements of the regulators.
From a technical point of view, there is no difference between connecting directly to the server or installing an intermediate mikrotik. Mikrotik is somewhat more convenient to set up, it is still tailored for this, plus it’s easier to change it separately and if you need to hide several real servers behind it, having a single setting (but also a point of failure).
It is easiest to forward an ip address to a container through several vlans (then each ip has its own virtual interface on the server) or through several ip addresses on the server (you need to look at which is simpler and the required isolation level).
You can skip in general transparently, i.e. by storing external addresses on the server, and by using address translation (1 to 1).

Answer 2

Well, decide on the structure of the network and what you want to get from it. Who knows better than you how best to set everything up?

Answer 3

Needed, and easy to set up.
Well, why does each container have its own ip - a separate question altogether
