PIX, VPN Accelerator Cards for AES

Hello,

I am about to choose the transforms for a huge VPN depoyment using PIX firewalls from 501 to 535 HA. Some of those firewalls will have VPN AC cards, others not.

Question, Are the VPN AC cards optimized for 3DES/DES or is it also bringing refreshing soda's for busy PIX using AES?

That post since I know some VPN Ac cards, like for Soekris firewalls are optimized only for DES/3DES. So I am wondering ;-)

Thank you very much,

Julien
