LARTC - Aug 2002 - uplink with multiple lines

I''ve been trying - without success - to aggregate the bandwidth of 3
DSL modems
using the instructions in the HowTo (sections 4.2.1 and 4.2.2).

I _believe_ I''m following the instructions to the letter, but when I
add the last command (the "ip route" with "nexthop") then
nothing goes out through the modems.

Each modem works when I add a single default gateway pointing to it, so I
don''t believe the modems are the problem.

Two of the modems _do_ have private IP addresses (192.168.x.1) - could that be
confusing the kernel? If so, do I need to get public IP addresses for those
modems?

Do I HAVE to create a patched kernel (ala Anastasov)?

May I post the script I used to try this out?

Thanks, folks!

	AFAIK, there is not flag "public" for the IP addresses in
Linux, at least, not in IPv4. The kernel does not know anything
about private/reserved IP ranges.

	May be not. But you can try to understand the settings
provided in the docs. The essential thing to understand is how
the ip rules and routes are ordered, how the NAT uses the
routing, why the NAT in plain kernels sometimes breaks with
multipath routes, what kind of nexthops the kernel can live
with, can you live without dead gateway detection, if not, how
it works (in kernel? help from user space?), etc.

	Or if possible to provide reference to it after the 5th
reading of all docs :)
