Dear All...

i'm quite new on Mikrotik...
now i have a RB450 with ROS 3.21
what i wanna do is to loadbalancing(NTH) from 3 DSL with PPPoE dial on RB450 en set all upload trafic to one interface that goes to another ISP (wireless).
Anyone could give me a simple word to make it possible ???

here are the simple plans

eth1 ADSL 1 -----------
|
eth2 ADSL 2 -----------
|
eth3 ADSL 3 ----------- RB450 ----------- eth5 Local
|
eth4 ISP(upload) -------


Thanks in advance

Andre

Please someone help me with my case...

What do you mean by 'upload traffic'?

What do you mean by 'upload traffic'?

Thanks for your respon...
what i mean is to routing all upload from local to 1 interface that goes to 1 ISP...
i have 3 DSL connection with 1024Kbps downstream and 128Kbps Upstream for each line...
and i have another 1 WISP with 1024Kbps Downstream and Upstream ...
Is that possible to make all download from 3DSL(NTH) and upload goes to WISP ?
sorry if i my sentences is confusing ...

No, or at least not how you're I think you're imagining it to work.

Simply put, upload/download really doesn't mean much, as connections are two-way - even when you're downloading something, you're uploading ACKs (acknowledgements that you've received packets) and when you're uploading something, you're downloading ACKs (acknowledgements that the other party has received your packets). You cannot run one over one circuit and the other over a second circuit as the endpoints of the two-way communication must be the same, and would change if you were to NAT to a different IP address (additionally, NAT only happens at the beginning of a connection and the second circuit provider would just throw away the packets with the wrong public IP address).

What you can do is take likely traffic that causes a lot of upload (like P2P) and use routing-marks to mark those packets, and then install routes that push packets with those routing-marks out the WISP way. The wiki has examples for that.

Thanks for your fewi
i already use trafic priority espessialy with heavy trafic....
it seem's that my thread is just a dream in Mikrotik...hope the Mikrotik's team will make it possible

It's already possible with Mikrotik. Just not in the way you imagine it can work. DEFAULT traffic out one path, then use policy routing to manually route the REST of the traffic out the other interfaces.

I should clarify. It is possible to use different paths for your network traffic. It is NOT possible to send traffic that is "upload" our outbound from your network always out one path and all downloads come back in on another path. If you are providing ISP services, this is why it is so bad to use consumer grade circuits.

thanks Butche...
now i understand how it work and how it can't work with the upload trafic...
my case is i have very small upload bandwidth from DSL and i have another subscription for a high upload bandwith...
any idea how to manipulate it's route or at least to improve my network performance ???

My suggestion would be to find a consultant that is local to you who is familiar with policy routing and QOS implementations. You can start that search here: http://www.mikrotik.com/consultants.html
