The setup I want to try is: NIC1 - ISP 1 DSL PPPOE connection NIC2 - ISP 2 DSL PPPOE connection NIC3 - GATEWAY TO LAN The LAN clients all have static IP addresses. I don't want to manually assign each LAN client to one ISP connection or the other. I would like to set up the routerbox to take care of all balancing tasks to optimize use of bandwidth provided by the two DSL accounts. I have spoken with tech. support at roaringpenguin.com and they confirm that their dsl connection client software is capable of maintaining multiple broadband connections. I just can't find anyone who's actually done it before and knows something about how to route the connections in conjunction with iptables rules. There's some pressure involved in trying this as, the network is on demand 6 days a week. So I won't have much time to run tests and try different configurations. Currently there are two LANs built around the 2 different dsl connections; however, it is becoming more and more apparent that the office will function much more efficiently by joining the 2 LANs into one. Any/all guidance is greatly appreciated. Thanks for your time. Mike
