Load Balancing Question, Please Help !

I am trying to combine 2 WAN links to have combined bandwidth for my LAN user’s.
My config is as follows.

IP Address Configuration

/ ip address add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=ether1 comment="" disabled=no
/ ip address add address=10.111.0.2/30 network=10.111.0.0 broadcast=10.111.0.3 interface=ether2 comment="" disabled=no
/ ip address add address=10.112.0.2/30 network=10.112.0.0 broadcast=10.112.0.3 interface=ether3 comment="" disabled=no


Mangle Configuration

/ ip firewall mangle add chain=prerouting in-interface=ether1 connection-state=new nth=5,1 action=mark-connection new-connection-mark=conn1 passthrough=yes comment="" disabled=no
/ ip firewall mangle add chain=prerouting in-interface=ether1 connection-mark=conn1 action=mark-routing new-routing-mark=conn1 passthrough=no comment="" disabled=no
/ ip firewall mangle add chain=prerouting in-interface=ether1 connection-state=new nth=4,1 action=mark-connection new-connection-mark=conn2 passthrough=yes comment="" disabled=no
/ ip firewall mangle add chain=prerouting in-interface=ether1 connection-mark=conn2 action=mark-routing new-routing-mark=conn2 passthrough=no comment="" disabled=no


Masquerade ether1 (Local) Network

/ ip firewall nat add chain=srcnat connection-mark=conn1 action=masquerade out-interface=ether2 comment="" disabled=no
/ ip firewall nat add chain=srcnat connection-mark=conn2 action=masquerade out-interface=ether3 comment="" disabled=no


Route

/ ip route add dst-address=0.0.0.0/0 gateway=10.111.0.1 scope=255 target-scope=10 routing-mark=conn1 comment="" disabled=no
/ ip route add dst-address=0.0.0.0/0 gateway=10.112.0.1 scope=255 target-scope=10 routing-mark=conn2 comment="" disabled=no
/ ip route add dst-address=0.0.0.0/0 gateway=10.111.0.1 scope=255 target-scope=10 comment="" disabled=no

The problem is all user’s traffic going through 1 WAN gateway only (i.e ether2) , traffic is not going though WAN2 (ether3) , I want to pass traffic equally from both interface. So even if any single user download any file, he must get bandwidth from both WAN interfaces.

What I am doing wrong?

Please Help!

Remember that when using nth, each new connection usually goes through the next gateway. If you open a web site, you will see for instance that some pictures and then ads will be fetched via different gateways. The closest you will get to bandwidth aggregation with this setup is when you download huge files with something like download accelerator or free download manager which opens multiple connections for a download. You then get an idea of what the benefits of running this setup will give you.

If you would like to combine two gateways into an aggregated device, the only thing i know of is multilink over pppoe if your provider supports it of course.
