My apologies, as I was not as clear as I should have been. Load balancing is not what I meant, I would merely like to assign two IP addresses that are on the same subnet to each NIC in the server. To be honest whether or not 1 NIC can handle the load is not my concern, I want to see if it is possible to have 2 IP addresses that are on the same subnet assigned to each NIC. The end goal is to split out the services to each interface. Please let me know if more information/clarity is needed.
