Problem

Site to site VPN's are great for main office to branch office connections, but for remote workers in a SOHO environment obtaining a static IP address can be expensive and time consuming. Traditionally remote workers will use either AnyConnect or IPSEC Remote VPN's.

However Cisco have a system which lets you have a main site (or sites), with a static IP, that acts as the EasyVPN server, then remote sites with dynamic DHCP IP addresses can authenticate and connect via a hardware device. That remote hardware device can be another ASA (Note: Only ASA5505 can be used as an EasyVPN client), or a Cisco IOS router. In addition if you have any old PIX 501 or 506E firewalls laying around they can also be used as EasyVPN clients.
