(I guess) I still look... as I also have two DSL lines I searched in for the same kind of information = in the past that you are trying to find. After hours of Googling I came to the following conclusion: - being "multihomed" with a FreeBSD based system is only possible if you use a dynamic routing protocoll. The required software suite for this is Zebra. Drawback: requires assistance from your ISP an *a lot* of routing knowledg= e on your side. Does not work with dynamic IP addresses usually assigned via PPP as seen with most non-business customers - being "multihomed" with a Linux based system does work to some degree if you use the IPChains/IPTables/IPRoute2 features that come with the OS (tagging packets to route them out on the same interface they came in by making routing decisions based on those tags etc.). AFAIK there is also an experimental pseudo NIC that is used to bundle the lines. Drawback (for me at least): I am not familiar with Linux :) - being "multhomed" independent of the type of OS works with hardware that is specifically designed to bring DSL or Cable lines together. One example for this kind of hardware would be Radware=B4s "Linkproof" pro= duct Drawback: this stuff is pretty expensive (compared to an open source software solution) So far I did not find any tutorial or howto or whatever to achieve my goal w= ith FreeBSD. I assume right now there is no satisfying way to use your two lines with BSD except with dedicated hardware.
