Is it possible to set up 1 vlan on multiple Mikrotik ports?

Question

Mikrotik

Greetings.
There is a Mikrotik router on ethernet 5 ports and a server with 1 Ethernet port which should become a Gateway.
The scheme is as follows:
1 port: wire from the provider
2,3,4 port: wires of local network clients
5 port: server
There was an idea to make 2 VLAN:
VLAN2: 1 port
VLAN3: 2,3,4 ports
and send both vlans to port 5, so that the server can already resolve them. Raise a static IP address on VLAN2, and distribute local IP and Internet in VLAN3.
How to implement this? And is it possible?
PS
Unfortunately, Mikrotik did not work as a gateway for LAN, so using it as a switch is a necessary measure.

Answer 1

Let's swim in the definition of what are Wealans!) Are there network cards with support for several Wealans?). Lots! Although crutches you fence the master!)

Answer 2

Here and here on the Mikrotik wiki it says how to set up vlans, they even gave an example, but I agree with the previous answer about the theory, if you start explaining, then there will be a lot of questions!
the first option is implemented using a switching chip, the second option is the VLAN handles the CPU
