Anyone have any thoughts on the potential for:

putting three nics in a Unix box, grabbing two DHCP addrs from
Roadrunner (in my case), with the first two nics, and using the third
as a natted default gateway for internal boxes. and load balancing
the two on a packet-by-packet basis?

Theoretically this would effectively double the bandwidth of a
connection behind the network. Throttled upstream say at 180kbit/sec
would go to a theoretical 360k/sec and the 1mbit/downstream would turn
into 2mbit/downstream.

I'm positive this will work but am curious mostly on what software
would be capable of doing this across two nics. I had considered one
nic but realised that no dhcp server in their right mind will assign
two IP addresses to one mac. I was thinking that perhaps I could run
gated with equal metrics ..or something like that..

thanks for all input.

Wouldn't you still get the same speed? The bottleneck is the Internet
connection, not the network....you will get information to and from the Unix
box faster, but it's still going to hit a brick wall when it leaves/enters
the cable modem. Also, I think the cable modem is the only device assigned
an IP address from the ISP, (cable company) and that the network cards are
the responsibility of the user, wether the user's network runs DHCP or
static IP addressing.

I don't think so, some isp use the MAC adress to identify user's machine.

No it won't be throttled as he said...Easy ip address you get is
assigned to a MAC and the server-side cable modem software determines
bandwidth limit based on MAC addr.

So I suppose the question is stilll:

What software to use to do this with....I've been looking around
freshmeat and sourcefourge but can't seem to locate it. I considered
two default routes but the kernel's (ifconfig) won't allow multiple
defaults (such as a Cisco would)..

Anyone with any more thoughts?

Thanks
