PPPoe server with problem in load balance

Made a server adding two links adsl and worked perfectly but customers who authenticates this server that uses as a basis for authentication pppoe not navigate, can see that after you connect it does not generate traffic in nat.

My scripts:

/ ip firewall mangle
add chain=prerouting connection-state=new src-address-list=Lista_1 in-interface=Lan0 action=mark-connection new-connection-mark=Cone_1 passthrough=yes
add chain=prerouting in-interface=Lan0 connection-mark=Cone_1 action=mark-routing new-routing-mark=rota_1
add chain=prerouting connection-state=new src-address-list=Lista_2 in-interface=Lan0 action=mark-connection new-connection-mark=Cone_2 passthrough=yes
add chain=prerouting in-interface=Lan0 connection-mark=Cone_2 action=mark-routing new-routing-mark=rota_2


/ ip firewall mangle
add chain=prerouting in-interface=Lan0 connection-state=new nth=1,1,0 action=mark-connection new-connection-mark=Cone_1 passthrough=yes
add chain=prerouting in-interface=Lan0 connection-mark=Cone_1 action=add-src-to-address-list address-list=Lista_1 address-list-timeout=03:00:00 passthrough=yes
add chain=prerouting in-interface=Lan0 connection-mark=Cone_1 action=mark-routing new-routing-mark=rota_1 passthrough=no

add chain=prerouting in-interface=Lan0 connection-mark=Cone_2 action=add-src-to-address-list address-list=Lista_2 address-list-timeout=03:00:00 passthrough=yes
add chain=prerouting in-interface=Lan0 connection-mark=Cone_2 action=mark-routing new-routing-mark=rota_2 passthrough=no


/ip firewall nat
add chain=srcnat connection-mark=Cone_1 action=src-nat to-addresses=192.168.7.254 to-ports=0-65535
add chain=srcnat connection-mark=Cone_2 action=src-nat to-addresses=10.0.0.254 to-ports=0-65535

/ ip route
add dst-address=0.0.0.0/0 gateway=192.168.7.1 routing-mark=rota_1
add dst-address=0.0.0.0/0 gateway=10.0.0.1 routing-mark=rota_2
add dst-address=0.0.0.0/0 gateway=10.0.0.1


The problem is when the client connects by pppoe it does not generate traffic in nats and client not navigate
