This has been discussed quite extensively on the list in the past, and if I recall correctly the answer is basically no, unless the lines go to the same ISP and they also configure the lines this way on their end. There may be various ways to dynamically dink your own routing table to try to balance your outbound traffic, but by the very nature of IP the inbound traffic cannot be regulated without full cooperation of the upstream routers. -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) Library Interchange Network (LINK) , (608) 266-6348
