Enter the pool of IP addresses that the Device uses to assign to the L2TP VPN clients.

DMZ, WLAN, or PPTP VPN subnet even if they are not in use.
Specify up to 2 LAN groups (subnets) which a L2TP VPN client is allowed to access. If
none is specified, all LAN groups can be accessed. Enter the IP address and subnet
mask for the LAN group(s).
Select how the Device authenticates a remote user before allowing access to the L2TP
VPN tunnel.
The authentication method has the Device check a user's user name and password
against the Device's local database, which is configured in the Maintenance > User
Account screen.
The Device sends a Hello message after waiting this long without receiving any traffic
from the remote user. The Device disconnects the VPN tunnel if the remote user does
not respond.
