I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

one physical NIC vs. two physical NICs
Keith AlabasterEnterprise ArchitectCommented:
ISA server is a good example in certain circumstances..
With one NIC, it can publish web and mail servers and act as a proxy but thats all. Traffic arrives on one nic and then leaves through the same nic.
With two nics, you can apply packet filters etc as the traffic has to pass through one interface and exits the other interface.
