5.3.4 IPSec VPN

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 can be configured to operate in two different modes, Tunnel and Transport mode. Use of
each mode depends on the requirements and implementation of IPSec.
IPSec VPN Server (Tunnel mode)
Tunnel mode is used to encrypt all traffic between secure IPSec Gateways, for example if you
have two DVX IPPBX's and each acts as an IPSec Gateway for the hosts/IP phones behind it. The
WAN ports will be used to connect both DVX systems to establish IPSec VPN connection, now all
PCs or IP phones on the LAN ports can communicate with each other on both sides via a secure
IPSec tunnel.
