Hi. I have RB750, and 3 interface configured:
1. LAN_ethernet, IP=192.168.0.1/28 (my comp got IP=192.168.0.7, and i have internet access)
2. ADSL1, IP=192.168.1.2/24, on this interface i have pppoe client ADSL1_pppoe (2Mbps)
3. ADSL2, IP=192.168.2.2/24, on this interface i have pppoe client ADSL2_pppoe (4Mbps)

I want to know, it is possible to make, when i downloading something on my computer (IP=192.168.0.7) with uTorrent, to use both ADSL1_pppoe and ADSL2_pppoe conection in tha same time. I mean, i want to download torrent file with 6Mbps speed. It is possible to make this, and how can i make this? Thanks for any help!

You are talking about bonding your ADSL connections and you can't do that. Now you could setup PCC and with uTorrent, since it uses multiple connections per file, possibly download at 6mbps. But surfing and "regular" downloading you will not be able to achieve a bonded throughput without BGP or such and I doubt your provider supports BGP through your ADSL.

thanks for quicky reply. i'm interested just about higher speed for uTorrent download, not for browsing too.

I would try PCC. Here is the link.

it is possible to make MLPPP here? i have same username and password for both pppoe client connections? will that solve my "problem"?? my ISP's are diferent, and i got different IP's from both ISP (not same range). How can i use PCC, when i sending packets just from one IP (192.168.0.7) not from many IP's? As i can see, now uTorrent downloads one file just from one source (from one IP), not from many sources. I use private torrent.
