I.e. the ADSL locations connect to the Static Location<br />
All three locations have UNIQUE LAN IPs.<br />
no overlap<br />

Which ASA? Have you checked Cisco's example for site-to-site VPN?

Hi, I have 3 sites in different geographical locations and we use Cisco ASA firewalls.
The main site has a static IP internet. The other two sites have dynamic IP ADSL lines.
How to configure the site to site IPSec VPN tunnels?
I tried configuring separate tunnel groups and necessary settings. Nothing works.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
