VPN
Overview
A Virtual Private Network (VPN) creates a secure, dedicated communications network tunnelled
through another network.
You can configure the IOLAN for:
z
a host-to-host Virtual Private Network (VPN) connection
z
a host-to-network VPN connection
z
a network-to-network VPN connection
z
or host/network-to-IOLAN VPN connection (allowing serial devices connected to the IOLAN to
communicate data to a host/network).
In addition to being able to configure up to 64 IPsec tunnels, you can configure an L2TP/IPsec tunnel
that will allow hosts to create a VPN tunnel to the IOLAN. The L2TP/IPsec VPN protocol is required
by the Windows XP
®
operating system. Later versions of Windows
®
may support both VPN
protocols, however check with the Windows
®
documentation that came with your Windows
®
pc.
