PIX515 run VPN - Need Upgrade ?

[khaiyang]

I need to run remote-to-site VPN with the expectation of 30 concurrent VPN sessions. Remote client will use the Cisco VPN client software, some users on Windows, some on RedHat. Do I have any issue to run the VPN solution (client software compatibility and PIX license ...) ?

As I understand .. Cisco VPN client does have linux version ....

I tried to apply Cisco Easy VPN on the PIX and Client PC, but seems like this requires at least PIX Firewall Version 6.2 or above.

I foresee that OS upgrade is surely a must to run this, do I need to upgrade to "PIX-515-VPN-3DES=" to run this setup ?
