How to assign one line only for upload

Hi,

I have routerboard CCR1036-12G-4S and i have 3 different internet lines (1- DSL 15 Mbps upload and download, 2- ADSL 16 Mbps download , 3- ADSL 16 Mbps download).
I need to know the possibility to assign only the DSL with 15 Mbps to be used for upload and not to use the other ADSL which I have.
is there any way to make priority for certain lines for upload or even download ?

Thanks

You are working with connections that transmit data both ways. Normally there is nothing like pure upload or download. You can break the connections and send all packets by whatever interface you wish but without some kind of bonding support on the other side of adsl links you cannot do what you think and expect it could work. Moreover you cannot select by what link the packets arrive at all.

Hi jarda,
Thanks for your reply and finally I found an article proof that you can assign an Upload wan and download another, please refer to the link below:

Yes, but it assumes that your ISP would cooperate on it (accept the spoofed ip address that does not belong to the dsl connection). This is not always expectable. Anyway, it is breaking the connections as each part goes trhu other way. I told you recently that you can do it this way. Just try it and be hapy if your isp accepts it… Every day can happen they will change their settings and disallow it. You cannot rely on such setting.
