pppoe client loadbalance & pppoe server

Hello everyone,
i have 8 pppoe Client from my ISP, and i would like to loadbalance them, and get the service out through an pppoe server.
at the moment i’m using two routers, one as a loadbalance and the other as a pppoe server.
about loadbalance method, i’m using nth method as shown in the attach images, and out interface through a static ip.
about pppoe server, in interface using static ip from loadbalance, and i have made queue tree rules to control users bandwidth.
my problem is, slow browsing, and i would like to know if i can use only one router to do both steps.
loadbalance router is RB493AH, pppoe server router is CCR1016-12G.
any help would be appreciated.

Warm Regards
Hayder

yes, i think u could

Google PCQ load balancing. Better way of doing this without breaking secure connections. Lots of howto’s. Also, yes. Possible to do on same router. Actually easier this way. Only difference you would use PPPoE interface instead of ether interface in load balancing.

yes, is possible use only 1 rb for all the task.
I suggest to use pcc instead of nth.
