I am assuming you want to use IPsec.  If so, you will need one of the IPsec
images for your router.  The encryption strength varies on the IPSec images
between DES and 3DES.  3DES is stronger.  

And yes, if you use IKE with the IPSec image, you can use either preshared
keys, RSA Keys or Digital Certificates.

Subject: 1720 w/VPN module and VPN client


We are trying to setup a 1720 w/VPN module, Firewall feature set, and Cisco
VPN client software in a "secure gateway tunnel" mode.
The questions I have, is will we need the 3DES feature set also?
And can we used a "preshared key" instead of certificates?
