Ipsec over NAT-T

Hello,

Just trying to learn a bit about Firewalls. Thought I'd be ready for it ... Just realized I'm not. But now I have to finish this test and need to document it.

It looks like this:

Computer --- Ipsec device 1 (Local network) --- radio router --- Internet --- Ipsec dev2 ( with static IP) --- computer for data

Radio Router (I don't know if this is the right name):

I have to activate Nat Traversal, right?

Do I need a static Route to the Ipsec device 2?

Ipsec device 2:

Do I have to activate Nat Traversal here, too?
