VPN

In order to create a VPN tunnel on Windows XP

®

 , you must use the L2TP/IPsec protocol. When 

L2TP/IPsec is enabled, the IOLAN will listen for L2TP/IPsec VPN tunnel requests.
When you enable L2TP/IPsec, you are requiring that all access to the IOLAN go through the 
L2TP/IPsec tunnel, so you must configure any exceptions first see (

 for more information 

on exceptions) or you will not be able to access the IOLAN through the network unless you are 
configured to go through the L2TP/IPsec tunnel (you can still access the IOLAN through the Console 
port).

Configure the following parameters:

When enabled, the IOLAN listens for L2TP/IPsec VPN tunnel connections. 
Note: to allow non-VPN tunnel connections to the IOLAN, you must create 

entries in the VPN Exceptions list.
Default: Disabled

If the IPsec local address is set to 0.0.0.0, the IOLAN will listen for 
L2TP/IPsec connections on (the IP address of) the network interface 

assocaiated with (ie: on the same network as) the IOLAN’s default gateway.  If 

no default gateway exisits, the IOLAN will not listen for L2TP/IPsec 
connections.
Default: 0.0.0.0

Specify the authentication method that will be used between VPN peers to 

authenticate the VPN tunnel.
Data Options:

z

Shared Secret—A text-based secret that is used to authenticate the IPsec 

tunnel (case sensitive).

z

X.509 Certificate—X.509 certificates are used to authenticate the IPsec 

tunnel. When using this authentication method, you must include the 
signing authority’s certificate information in the SSL/TLS CA list and 

download it to the IOLAN.

Default: Shared Secret
