[LARTC] Question about Bonding interfaces under Linux

[jean-philippe.le-henaff@socgen.com]

I have a question about bonding 2 interfaces to 'load-balance' my 2
connections on Internet.
I have 2 differents Providers (and IP class) with dhcp addressing.
I tried a lot of things with ip+tc and also iptables, but nothing worked.
My question is how to set up my connection to be able to use both
interfaces to double my connection speed.

My network is something like :

                                                                 ________
                                          +------------+        /
                                          |            |       |
                            +-------------+ Provider 1 +------- 163.1.x.x
(dhcp)
        __                  |             |            |     /
    ___/  \_         +------+-------+     +------------+    |
  _/        \__      |     eth0     |                      /
 /             \     |              |                      |
| Local network -----+ Linux router |                      |     Internet
 \_           __/    |              |                      |
   \__     __/       |     eth1     |                      \
      \___/          +------+-------+     +------------+    |
                            |             |            |     \
                            +-------------+ Provider 2 +-------  82.18.x.x
(dhcp)
                                          |            |       |
                                          +------------+        \________

Thanks.
