Let me see if I can paint a better picture. I work for a school district and each school that is accessing the internet from this particular location gets routed out a particular dsl line according to usage stats. So right now the 2801 is setup to do pbr to each of the linux dsl routers that I have behind it. The linux dsl routers are connecting to my isp through the modems provided. The linux dsl routers are standard workstations converted to do pppoe/nat/routing/queueing. I would like to simplify this configuration with some kind of cisco hardware. The reason I have 4 dsl lines is because there is nothing else available in my location. I now have the 827 working and I have replaced one of the linux boxes and modems with that unit instead. This will be a little better but I would have like to use the 2801 to do everything.
