[c-nsp] Best Practices for Enterprise networks

[Tracy Smith]

Hello.  I am tyring to gauge what the Best Practices are for Enterprise network connections to the Internet.  Specifically, to NAT or not to NAT?  At what point should NAT-ting be performed ... exclusively at the Egress point or at decentralized points?  What about firewalling - centralized/decentralized?

Thanks in advance for any feedback!
