Hello I am using load balancer, modem goes to load balancer but I am not using two or more Internet lines, yet.
My problem is, my load balancer has ability that is called Multi DMZ.
I have completely forwarded Load Balancers WAN1 port to Mikrotik.
Afet I forward it, internet connection goes off.
Now, router needs to take main WAN IP from LAN IP like:
195.174.222.222-192.168.1.1-192.168.1.2-195.174.222.222

So, I couldn't did that thing. I know you didn't understand it clearly, also I didn't understand the situation as well.

If you REALLY want to use loadbalancing, why not use MT instead of third party loadbalancers?

Search for the ECMP script on the MT WIKI. I do not trust loadbalancing. I make use of src-routing and dst-routing, much more stable and reliable.

I reckon loadbalancing is fine for WISPS with fewer clients, but it's a risk you have to take.
