8.1.1 Set-up principles
 VPN server set-up
If the ETIC router behaves like a VPN server, it means that the ETIC router has to receive at least one ingoing
connection, the set-up has to be carried-out in two steps :
Step 1 : Configuration of the parameters of the OpenVPN server.
Only one server can be set-up.
Step 2 : Configuration of the ingoing, and possibly outgoing, connections.
The VPN server is unique; it can accept up to 25 ingoing connections from VPN clients.

VPN client set-up
If the ETIC router behaves only like a VPN client, the set-up consists only of configuring the outgoing
connection (one or several).

Set-up rules
Common parameters
The following parameters are common for the server and for all the clients supposed to set a VPN to that
server :
Transport protocol (UDP or TCP) and port number.
Encryption algorithm (Blowfish, AES 256, AES192, AES128, 3DES).
Authentication (MD5, SHA1).
IP domains
The IP domain of the LAN and of the remote LAN must be different.
Example :
LAN network :
192.168.1.0 netmask 255.255.255.0
Remote LAN : 192.168.2.0 netmask 255.255.255.0
