Hi All,
Does anyone have any experience connecting two or more DSL/Cable modems to a Linux box to provide load balancing and failover?
I've done some googling and found a few resources but very few solid experiences.
I'm trying to optimize my LAN->Internet traffic for a bunch of workstations.

I haven't tried this on linux but it appears trivial in OpenBSD: http://www.openbsd.org/faq/pf/pools.html#outgoing
I personally prefer OpenBSD for firewalls/gateways over Linux. I love linux for pretty much all purposes except firewalls/gateways, and I don't use OpenBSD for anything other than firewalls/gateways. Mainly because of packet filter(pf), it's a wonderful tool.
I tried looking at some documentation for iptables for doing the same thing but it was pretty vague. I didn't notice anything similar to what pf can do in the document above. Closest I found was: http://www.netfilter.org/documentation/HOWTO//NAT-HOWTO-6.html#ss6.3
Which says if a range of IPs is given it can balance based on the least currently used IP. But no indications of whether or not you can use IPs from different subnets(from the above, I assume not).

I did this a couple of years ago with dsl and a cable modem. Take a look at the Adv-Routing-HOWTO on tldp.org.

I'd suggest using PfSense for that. It is based on FreeBSD, but using OpenBSD's PF as packet filter. Commercial grade features in this free firewall, definitely a lot easier to configure and maintain than a linux box for this kind of tasks.
