I just read that, if you use an end-to end connection such as IPSec between a remote computer and a computer at work and your work network uses private IP addressing and NAT, that both computers will need to be configured with addresses that are internet routable. This is because the the addressing cannot undergo translation. Is this true? Isn't there a way to use private addressing in an internal network and still use a point-to-point connection? Forgive the ignorance. Studying makes me ask these questions.
