General Description

An advantage of using a powerful industrial router is the ability to send and receive data securely over an encrypted connection. This offers a user the ability to keep data secure between two endpoints by allowing the connected equipment to send data across an encrypted network connection securely without any changes to the configuration of the equipment using well defined security protocols. This document explains how to connect the Siretta router family to a server over an IPSec VPN tunnel.

The Siretta range of Industrial Routers support the followings VPN protocols:

  • GRE
  • OpenVPN Client
  • L2TP/PPTP Client
  • IPSec

These details are available from your network administrator for your VPN server.

NOTE: If you do not have your VPN Server details to hand then you can obtain temporary test details from the following link ‘‘ to allow you to check the VPN functionality of the router.
