Cisco PIX & ISO Firewall site-to-site VPN

Asked by Pro4ia in Virtual Private Networking (VPN), IPSec Security Protocol, Cisco PIX Firewall

Experts,

I'm trying to get a Cisco PIX 506E and a device running Cisco IOS Firewall to connect to each other via VPN.  I can't seem to get the two talking and was wondering if someone can help me out.

Here is the setup
