I recall this required some special kernel configuration directives: CONFIG_IP_ADVANCED_ROUTER=y CONFIG_IP_MULTIPLE_TABLES=y CONFIG_IP_ROUTE_MULTIPATH=y and the "iproute" toolset, which must be installed separately; and a few other changes. I wonder if the same (if not more advanced) could be accomplished with FreeBSD. Take for example, Company A who wants to provision a few sDSL lines. Creating a FreeBSD gateway/router and load balancing the traffic amoungst that (with some careful ipf or ipfirewall rulesets) could be very effective, and a lot cheaper than provisioning a single pipe in some cases. One could take multiple connections like dialup, dsl and cable modem and make the most out of that as well. I wonder if anyone has accomplished this with FreeBSD-4.x or 5.x; and if they could share that info.
