Re: Fw: IPSec vs. SSL
You are right there is no fundamental need unless the business requires it.
Purely an example of scalability and control using IPSec rather than SSL.
SSL is dynamic wheras IPSec needs setup and maintenance.

Why? There is no reason why all of them have to exist simultaneously,
unless there is actually traffic flowing on all of them... and in any
case, there is no n*n-1 on any single machine. You could equally say that
there would have to be n*n-1 TCP connections involved, and nobody
complains about that.
I agree that n*n-1 gets troublesome if there needs to be explicit
per-tunnel management or configuration, but there is no fundamental
requirement for that.
