Re: Load balancing with multiple ADSL connections?

Hi!

We are having some difficulties here to find a good solution for a
problem. There is a computer connected to 3 ADSL lines (two of 8M and
one of 2M), a card to the internal network and in the future, a new
card, connected to a radio link (giving 4 connections to the world and
one connection to our network).

What we want to do is to have some kind of load balancing and fail
over on the available links (so all links get used and if one have a
problem, the traffic will continue on the other links). Also, we would
like to have a priority system, where traffic is sent preferably on
the two 8M links, then on the 2M link and lastly, on the radio link.

Lokiwall [1] seems the tool that we are needing, but it needs to have
two patches applied to the kernel (and if possible, we don't want to
modify our firewall Kernel).

Do somebody knows if it's possible to do this (and how to do this), please?

Yes it is posisble thought it was some time ago i have done something like this. You need to patch the kernel or there is problems with packets coming out of the wrong interface when you are doing nat with several different external interfaces. If you have the lines bonded and you only see 1 ip address returned from the service provider or have proper routring setup with the isp's that you terminate with then it should work without patching.
