4.3.4 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.
4.3.4.1 IPSec VPN Server (Tunnel mode)
Tunnel mode is used to encrypt all traffic between secure IPSec Gateways, for example two IP
PBX's, each acts as an IPSec Gateway for the hosts/IP phones behind it. The WAN ports will
be used to connect to each other to establish IPSec VPN connection; the PCs or IP phones on
the LAN ports can communicate with each other on both sides via secured IPSec tunnel.
Check the IPSec radio button to configure IPSec VPN server.
