    Well and what are your questions?
    Are it routers or PIX/ASA's?

        I still don't know what you are looking for. Maybe it's because of my English but ok...

        Do you want to know more about cryptography?
        In that case start with the basics or read some good books about cryptography.

        Do you want to know how to configure a LAN-to-LAN connection between to Cisco Routers?
