BLACK BOX® CS Installation, Administration, and User’s Guide 13

VPN

The CS administrator can set up VPN connections to establish an encrypted

communications between the CS and a host on a remote network. The

encryption creates a security tunnel for a dedicated communications.

You can use the VPN features on CS to create the following types of

connections:

• A secure tunnel between CS and a gateway at a remote location so every

machine on the subnet at the remote location has a secure connection with

CS.

• Create a secure tunnel between CS and a single remote host

To set up a security gateway, you can install IPSec on any machine that does

networking over IP, including routers, firewall machines, application servers,

and end-user machines.

The ESP and AH authentication protocols are supported. RSA Public Keys

and Shared Secret are also supported.

For detailed information and procedures to configure a VPN connection, see

“VPN Connections” on page 176.

Packet Filtering on CS

The CS administrator can configure the box to filter packets like a firewall. IP

filtering is controlled by chains and rules.

Structure of IP Filtering

The Firewall Configuration form in the Web Manager is structured on two

levels:

• The view table of the “Firewall Configuration” form which contains a list

of chains.

• The chains which contain the rules that control filtering.
