Im not sure if that applies to a pix to pix connection, or as they list it, a site to site connection. will it apply to that?

lrmooreCommented:
Yes, it applies to site-to-site (hardware-based) regardless of what is at the other end - pix, router, vpn3000, other firewalls, whatever.
How many are you looking at supporting?

2000 is your answer.
With a 515 (200MHz) and not a 515E (433MHz) you will notice a performace hit when using a high number of IPSEC connections with a high level of encryption AES 256, 192, 128 or 3DES.

It will only be 3 at the moment, so it's sounding like I should be good to go. Thanks!
