DVX IPPBX
98 / 130
Protocol:You can choose eitherUDP or TCP. Stealth requires TCP only so if you havestealth
enabled then this option is not configurable and the Server will use TCP by default.
Device Node:TUN or TAP; A TAP device is a virtual Ethernet adapter, while a TUN device is a
virtual point-to-point IP link.
Cipher:Cipher (or cypher) is an algorithm for performing encryption or decryption.
Compress Lzo:LZO is an efficient data compression library which is suitable for data
de-compression in real-time.
TLS-Server: TLS is an excellent choice for authentication and key exchange mechanism of
OpenVPN.
Remote Network:OpenVPNremote network.
Route:The route entries adjust the local routing table, telling it which network to route over
the VPN.
Client-to-Client: Client-to-Client can enable intercommunication between clients.
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.
Navigate to web menu Network Settings->VPN Server. Check the IPSec radio button to configure
IPSec VPN server.
