Several white ip on mikrotik. Is there an alternative to labeling packages?

Question

network hardware

Good afternoon. We have a microtik router. The provider gives a pool of addresses.
For subnets of different purposes, vlans are made. How to properly organize Internet access from different external ip for different vlans? Is this only possible using package tagging (mangle)?

Answer 1

simple routing to the internal (virtual) interface on which the microtic will have one IP (which for the rest of the hosts on this network will be the default gateway) does not suit you? DMZ in its purest form.

Answer 2

Each vlan is an interface in the understanding of Mikrotik. Write nata rules for each vlan group with different ip for each group. Specify the list of required vlans in "In interface", and the action src-nat with the desired IP.

Answer 3

Instead of marking in the mangle, you can create routing rules in /ip routes rules. RouterOS is able to make decisions about routing through certain tables for certain source addresses and interfaces.
