Virtual Private Networking (VPN)

Creating a Virtual Private Network

What is a VPN?

A VPN provides secure communications typically over the Internet by creating a secure

tunnel between two or more VPN routers (gateways) also known as a site-to-site VPN or

between a single client computer and a VPN router (gateway) also known as a client-

server VPN.

On your VPN router, only the following type of tunnel can be created:



Client-Server VPN

–

A single client computer or device with VPN client software

installed connects to a VPN router (gateway) allow the single client computer

or device to securely communicate to the LAN network of the VPN router over

the Internet.

Tunneling methods supported by your router:

SSL VPN

–

This type of VPN is most commonly used in Client-Server VPN applications.

Most modern operating systems may already include a built-in client software however,

your router uses an SSL VPN implementation developed by OpenVPN which will require

the installation of the OpenVPN client software supports operating systems such as

Windows® XP and later (32-bit/64-bit) and Linux. One major benefit to using the SSL

protocol for VPN is that most networks allow the SSL protocol to passthrough which

eliminates the requirement for special rules or configuration such as PPTP/L2TP/IPsec.

Important Note:

For any tunneling or VPN method used, to avoid IP address conflict and

to ensure connectivity, it is required that each end (LAN IP network or single client) of the

VPN tunnel is configured with a different IP network or subnet.
