Configuring a Virtual Private Network

You can configure the IOLAN to act as a Virtual Private Network (VPN) gateway using the IPsec 
protocol. Any of the following scenarios can be configured using one IOLAN and a host/server 
running IPsec software or two IOLANs, each acting as the VPN gateway. All the examples have 

 enabled, since both VPN gateways are running through routers.

The following example shows how to configure an IPsec tunnel between serial devices connected to 
the IOLAN and a host/network. 

 is enabled in this example (on both sides) 

because the VPN tunnel is going private network to public network to private network. This example 
uses an RSA signature for the authentication method, so the steps required to configure the 
authentication are in this example.
