Chapter 4 Create Secure Connections Across the Internet
To manage the ZyWALL through the L2TP VPN tunnel, create a routing policy that sends the
ZyWALL's return traffic back through the L2TP VPN tunnel.
• Set Incoming to ZyWALL.
• Set Destination Address to the L2TP address pool.
• Set the next hop to be the VPN tunnel that you are using for L2TP.
If some of the traffic from the L2TP clients needs to go to the Internet, create a policy route to send
traffic from the L2TP tunnels out through a WAN trunk.
• Set Incoming to Tunnel and select your L2TP VPN connection.
• Set the Source Address to the L2TP address pool.
