L2TP VPN
L2TP VPN uses the L2TP and IPSec client software included in remote users’ Android, iOS, or
Windows operating systems for secure connections to the network behind the ZyWALL/USG. The
remote users do not need their own IPSec gateways or third-party VPN client software. For
example, configure sales representatives’ laptops, tablets, or smartphones to securely connect to
the ZyWALL/USG’s network. See Chapter 33 on page 598 for more on L2TP over IPSec.

29.1.1 What You Can Do in this Chapter
•Use the VPN Connection screens (see Section 29.2 on page 539) to specify which IPSec VPN
gateway an IPSec VPN connection policy uses, which devices behind the IPSec routers can use
the VPN tunnel, and the IPSec SA settings (phase 2 settings). You can also activate or deactivate
and connect or disconnect each VPN connection (each IPSec SA).
•Use the VPN Gateway screens (see Section 29.2.1 on page 541) to manage the ZyWALL/USG’s
VPN gateways. A VPN gateway specifies the IPSec routers at either end of a VPN tunnel and the
IKE SA settings (phase 1 settings). You can also activate and deactivate each VPN gateway.
•Use the VPN Concentrator screens (see Section 29.4 on page 556) to combine several IPSec
VPN connections into a single secure network.
•Use the Configuration Provisioning screen (see Section 29.5 on page 558) to set who can
retrieve VPN rule settings from the ZyWALL/USG using the ZyWALL/USG IPSec VPN Client.
