Yes, I am aware of that. However, that makes shaping multiple independent "streams" going through one interface much more difficult. The only other thing I can think of is setting up a dummy network device and giving it the IP addresses on all the non-primary subnets (e.g. multiple DSL lines), and setting up the arp and routing to make the packet actually go via the primary interface. However, therein lies another problem - it means that the primary (real) interface (with the first subnet) could then not be shaped properly (I THINK), because shaping it would shape the overall traffic on that interface, and not only the traffic on the primary connection. So, the solution might be to set up the real interface with a dummy IP address, and assigning all valid, real subnets to the dummy interfaces, and set up the routes for those subnets to go via the real interface, and set up arp to make sure things go via the real interface. Has anybody got any thoughts on this? If this would work, maybe it should be documented in the advanced routing howto, as I can see how there might be a lot of people out there who would find it useful. Regards.
