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.
