I figured everything out, here some nonsense is written in these lines
delay_pools 2
delay_class 1 1
delay_class 2 3
delay_access 1 deny all
delay_access 2 allow lan1
delay_access 2 deny all
delay_parameters 1 -1/-1
delay_parameters 2 -1/-1 300000/300000 300000/300000
corrected for this, everything worked
delay_pools 1
delay_class 1 1
delay_access 1 allow lan1
delay_parameters 1 -1/-1 (set your own)
