Policy Route
The Policy Route for return traffic (from LAN to L2TP clients) is automatically created when Zyxel Device
adds a new L2TP connection, allowing users access the resources on a network without additional
configuration. However, if some of the traffic from the L2TP clients needs to go to the Internet, you will
need to create a policy route to send that traffic from the L2TP tunnels out through a WAN trunk. This task
can be easily performed by clicking the Allow L2TP traffic through WAN checkbox at
Quick Setup
>
VPN
Setup
>
Allow L2TP traffic through WAN
.
