I need to desing the outer firewall for my company. Now i'm doubting about the design and about the product choice.
The situation is
We have a provider equipment facilitation 2 ports at the inside. One for internet and one for our brache offices. I need to create 2 DMZ on that firewall. Is it sufficent to do it with a ASA 5510 or do I need to use ASA 5520, as we will in a later stadium high availability.
I will include 2 drawings of phase 1, and phase 2 as i see it.
Is the design correct?
Can anyone help me with this one.
