nth load balancing more odd than even

RouterOS Beginner Basics
1

I am doing nth load balancing on a MK450G. I have a DSL + Cable internet connection both with dynamic ip.
The load balace is workng but I see much more odd than even connections. As a result I have more traffic on one interface and very little on the other.

Please give me some advise.

I’m a bit rusty at this, but it seems that you have rules that add the src-address to each address list (odd and even). It appears that as each client makes a new request, the src-address (client ip) is added to each address list depending on the packet order.

So one client (src-address) should quickly end up in both lists. True? If so, then your first rules evaluate address-list=odd first, so most traffic will go out odd.

Or am I wrong? You might want to check “/ip firewall address-list” to verify that.

list is empty

Export doesn’t show dynamic entries. Use “/ip firewall address-list print”.

See the list below. I notice that my gateway address is showing up in the list (10.0.0.138).

[quote=“aislecom”]See the list below. I notice that my gateway address is showing up in the list (10.0.0.138).

Did you find any solution to your problem?

I am facing the same thing.
