Hi guys,
Im new with Mikrotik technology, I read about load balance, but Im not set up well my scenario, I have two routers one of them with static IP and other one with dynamic, I setup internet acces without NAT, so I connected to microtik in mode PPOE.
I observe stange performance, in my configuration mode, only work PPOE1, and only can acces across internet to PPOE1, PPOE2 dont work properly, can not access across internet, and client dindt use… only work PPOE2, when PPOE1 down, but not boths at same time 
… I think routes and mangle are OK…
I paste my configuration If some body can help me, I had hinking about that for long time and dindt found solution…
