Load balancing based on PCC gives me crazy on lan.

Hi!
I want make a load balancing between two wan’s (wan1 - 20mbit and wan2 -10 mbit).
I followed some tuts on internet and load balancing works fine, but in network i have timeouts, some strange hops in ping etc..My zabbix goes crazy if i enable this load balancing.(tcp ports innacessible in lan etc).
What is wrong?

SOLVED BY ADDING IN MAGLE

add action=accept chain=prerouting comment=“accept lan” dst-address=192.168.5.0/24

Have a look at this presentation: https://www.youtube.com/watch?v=67Dna_ffCvc (slide links available there)

I have smilar config to presentation, only change is PCC, not traffic monitor switch…

I meant to fully understand what needs to be accomplished on the LAN side.
