We are looking to implement a Satellite system that will be used for disater recovery. Any data going across this link must be encrypted. I am trying to find out what will be the best way to design this.

I a looking a several scenorios:

Router ============= Router (IPSEC)

Pix ============= Router (Pix having VPN Accel..)

VPN Concentrator=========Router

I am also going to have a Wireless LAN setup as well as part of the disater recovery. Which of these devices will give me the best performance and flexability.
