Hi group,

I have been looking for how-to or info on equal cost multipath routing
but have not had any luck. I have found out that I will have to
recompile
the kernel "that's ok can do" but how do I config multipath routing and
will ipchains still work for fire walling?

I wish to share two cable modems from same ISP for out going connections
only. Mail will run on one interface only. System will be used to
firewall a lan on a 3rd interface.

Disto will be RH6.2 with the 2.2.17-14 kernel and all required security
updates.

Thanks for any help.

I am not sure whether this will be help for you, but you might like to look at
the following URL:

I found this how-to already and it is for ppp serial modems.

Thanks for trying anyway

Wayne :-)

I have done a bit of digging around and found this thread back in 1999 on
Equal Cost Multipath Networking. The URL is located here:
http://mlarchive.ima.com/linux-net/1999/3376.html

Basically, it says that you have to recompile the kernel with
CONFIG_ROUTE_MULTIPATH enabled and then you can place two default routes in
the routing table. The system should then load-balance between them.

Personally, I am not sure whether this approach works, because most of the
dcoumentation I run into states that BGP routing would be a more effective way
of doing this (although that gets very pricey very fast).

Anyway, you might like to check out the document and see whether or not it
sheds any light on what you want to try and do.

See ya
