I have 3 customers using an 11503 with 6 interfaces. To maximize the throughput for each customer I want to separate the customers to their own interface. Each customer would get a client side and server side interface. From a load balancing perspective I believe this will work because the flow (src IP,Port, Interface & dst IP,Port,Interface) will match the client with the correct server response. My concern is when a server initiates a connection to another device and has to go through the CSS. I would like to have the customer's server use the corresponding client side iterface when initiating traffic. This way each customer gets a gigabit connection for themselves. I'm running 8.1 and it allows me to add multiple default routes but I don't see a way of having the CSS separate this traffic for each customer interface without specific static routes. Are specific static routes for each customer the only solution?
