6.4.3 VPN- Configure
Internet protocol Security (IPSec) is a standard based VPN that offers flexible solutions for
secure data communications across a public network like the Internet. IPSec is built around a
number of standardized cryptographic techniques to provide confidentiality, data integrity and
authentication at the IP layer.
A VPN tunnel is usually established in two phases. Each phase establishes a security
association (SA), a contract indicating what security parameters wireless router and the
remote IPSec router will use. The first phase establishes an Internet Key Exchange (IKE) SA
between wireless router and remote IPSec router. The second phase uses the IKE SA to
securely establish an IPSec SA through which the wireless router and remote IPSec router
can send data between computers on the local network and remote network.
Before IPSec VPN configuration, you will be involved with such terms like IPSec Algorithms,
Authentication Header and ESP protocol.
