Cisco 801 instead of software VPN Client on a PC

Hey,

i want to use my old Cisco 801 instead of the VPN Client on my PC.

The network looks like:

PC--\\ |--ADSL Router (NAT)----Internet --- PIX

I can use the Cisco software VPN Client on my PC to connect to the PIX.

I want to use the Cisco 801 to setup a connetion to the PIX, but i can´t find documentations for using IP-SEC with a group, group-password, user and user-password on an IOS-device.

Is it possible to use a 801 instead of the software VPN Client? How to setup the 801?

Thanks

Paul
