I have the same problem. I found a message about something similar on this
list (mail titled Re: [LARTC] Combining bandwith of two or more ADSLs ?,
dated april 10, 2001) but this didn't work for me:
I once had traffic over 2 interfaces (2 pings to different systems) but
after stopping and restarting the ping, they both took the same interface
out. I also noted traffic coming in on interface 1 and going out of
interface 2 (don't know why).
If I had sufficient hardware, I think that I would insert several extra PC's
with routing-software (www.zebra.org, since gated dumps core on me) and get
BGP or OSPF:
+--------+ +--------+
| adsl-1 | | adsl-2 |
+--------+ +--------+
\ /
\ /
\ /
\ /
\ /
\ /
\ /
+--------+
| proxy |
+--------+
|
|
|
+-----------------------+
| Lot of other machines |
+-----------------------+
I did notice that when you have 2 BGP-routers both advertising a default
gateway, the system only uses 1. If this one fails, it starts using the
second but it won't switch back when the original comes back up again. I
have not yet played with OSPF but in theory, this should allow for some
load-balancing too.
