From 3 to only 2 internet connections

RouterOS General

Hi!

I have 3 different internet connections on my Mikrotik, ISP1,ISP2 &ISP3.
I want to divide traffic on 2 pieces, one kind of traffic must pass via ISP1 and other traffic must pass via ISP2& ISP3 to internet.
So, how system may know only 2 main pieces of connections. One is ISP1 and other ISP2&ISP3.
Reducing from 3 internet connection to 2 software ones, one is ISP1 and other ISP2+ISP3

Any idea?

Thank you.

What “one kind of traffic” do you want to isolate through ISP1?

Hi SurferTim
Thank you for your reply.

With “Kind of traffic” I mean:
via ISP1 I want ot pass only DNS, ICMP, HTTP, HTTPS traffic and via ISP2 & ISP3 must pass other traffic.
Meanwhile, with help of a script will monitor load of ISP1 interface, if ith will be loaded more than 10Mbps, new HTTP requests traffic must pass via ISP1 and ISP2.
But, how may ISP2 & ISP3 serve like only one connection?

That is a big bag of requests. How about solving a couple at a time.

I think what you will need is routing-mark in
/ip firewall mangle

You will need to routing-mark the specific protocols correctly first. Take a look at the docs on mangle and routing-mark (not packet).

ADD: When (not if) you have questions, post them here. It is better for you to know about the procedures and options first.
