The product series supports following tunneling technologies to establish secure
tunnels between multiple sites for data transferring, including IPSec, PPTP, L2TP
(over IPSec) and GRE. Advanced functions include Full Tunnel, Tunnel Failover,
Tunnel Load Balance, Net BIOS over IPSec, NAT Traversal and Dynamic VPN.
4.2.3.1 Configuration
To enable the VPN function, you should go to Configuration before any setting.
4.2.3.2 IPSec
Internet Protocol Security (IPSec) is a protocol suite for securing 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.
An IPSec VPN tunnel is established between IPSec client and server. Sometimes, we
call the IPSec VPN client as the initiator and the IPSec VPN server as the responder.
There are two phases to negotiate between the initiator and responder during tunnel
establishment, IKE phase and IPSec phase. At IKE phase, IKE authenticates IPSec
peers and negotiates IKESAs(Security Association) during this phase, setting up a
secure channel for negotiating IPSec SAs in phase 2. At IPSec phase, IKE negotiates
IPSec SA parameters and setsup matching IPSec SAs in the peers. After these both
phases, data is transferred between IPSec peers based on the IPSec parameters and
keys stored in the
SA database.
4.2.3.2.1 IPSec VPN Tunnel Scenarios
There are some common IPSec VPN connection scenarios as follows:
•
Site to Site
The device establishes IPSec VPN tunnels with security gateway in head
quarters or branch offices. Either local or remote peer gateway which can be
recognized by astatic IP address or a FQDN can initiate the establishing of an
IPSec VPN tunnel. Two peers of the tunnel have their own Intranets and
these cure tunnel serves for data communication between these two subnets
of hosts.
