I'm working on a high-security, datacenter application design and was wondering if this is possible. If I have a server with 4 NIC's, All Gigabit. I'd like to pair them up as the internal and external interfaces for performance load balancing. I'd use the NIC manufacturer's Teaming SW to do this. Does ISA Server have a problem with a Teamed NIC for External and Internal Interfaces? Has anyone done this? Thanks, -Russ
