Mikrotik setup - 3 providers, 3 users in one local network; how to direct users correctly?

Question

Mikrotik

There is a Mikrotik.
There are three incoming lines (PPPoE1, PPPoE2 and PPPoE3).
Users 192.168.88.1-192.168.88.203 go through 1.
User 192.168.88.204 go through 2.
User 192.168.88.205 go through 3.
It is necessary that 204 and 205 can be connected via ports 22, 80, 443

. , set up port forwarding, sent 204 and 205 in the right directions, but you can’t connect to them on the right ports.

Answer 1

Concerning the first - policy base routing. It is not required to climb into the mangle in such a simple case.
As for the second one, first of all, look at the firewall rules, and keep in mind that it is applied on dst-nat before the filter, that is, the filter rules should be applied on the forward chain. This is provided, of course, that the nat rules are configured correctly.

Answer 2

You can try the implementation by groups, 3 groups for each group by wan. It was practically the same for me initially, but in 2 groups and 2 vans. But then I decided to implement it via dhcp. I specify which ip climbs into which wan.

Answer 3

You need to look in the direction of traffic marking, mangle.
