Network Extension Mode

Network Extension Mode with Split Tunneling

You always assign the VPN 3002 to a client group on the central-site VPN Concentrator. If you enable split tunneling for that group, IPSec operates on all traffic that travels through the VPN 3002 to networks within the network list for that group behind the central-site VPN Concentrator. PAT does not apply.

Traffic from the VPN 3002 to any other destination than those within the network list on the central-site VPN Concentrator travels in the clear without applying IPSec. NAT translates the network addresses of the devices on the VPN 3002 private network to the address of the VPN 3002 public interface. Thus the network and addresses on the private side of the VPN 3002 are accessible over the tunnel, but are protected from the Internet, that is, they cannot be accessed directly.

VPN 3000 Series Concentrator Settings Required for Network Extension Mode

For the VPN 3002 to use Network Extension mode, these are the requirements for the central-site VPN Concentrator.

1.The VPN Concentrator at the central site must be running Software version 3.0 or later.

2.Configure a group to which you assign this VPN 3002. This includes assigning a group name and password. See Chapter 14, User Management, in the VPN 3000 Series Concentrator Reference Volume I.

3.Configure one or more users for the group, including usernames and passwords.

4.Configure either a default gateway or a static route to the VPN 3002 private network. See Chapter 8, “IP Routing” in the VPN 3000 Series Concentrator Reference Volume I.

5.If you want the VPN 3002 to be able to reach devices on other networks that connect to this VPN Concentrator, review your Network Lists. See Chapter 15, “Policy Management” in the VPN 3000 Series Concentrator Reference Volume I.
