2 PPPoE input 1 Lan Output problem

hi there all
i have 2 adsl connection with diferent ISP
i alredy did setup 2 pppoe in my rb450 os 4.5
then in IP route i add a new route and as gateways i choose more than 1 gateway
i asign the 2 pppoe as gateway for my lan port

it looks ok

both of conections are used at same time
they do load balance and fail over at same time

but im getting problems in some online comunittis
facebook and its applications like texas hold em up i get disconected
same problem with youtube it stoops loading sometimes
another thing is that i cant reach maximum download
trafic of both pppoe 2M+2M i shoud get 4M output but max i got was 2.9M
any suggestion how to resove this problems

thanx in ADV

As far As I understood you are using ECMP. With this approach you will not get exact 4MB because ECMP is not per packet load balancing.

You need to set up PCC it will solve problems with disconnects

the problem is that im using PPPoE with dynamic ip
and the ppc need a ip interface so a my configuration the following


ip address
Abissnet PPPoE on ether 1 (on this pppoe connection i get always same ip)
Abissnet2 PPPoE on ether 2 (on this connection everery time i reconect i get another ip)
192.168.0.254/24 ether 3

im using rb 750


please post a configuration with the based on this connections
thanks in adv

And so where is the problem? As pppoe is point to point you can set interface as gateway instead of IP address.
