LABEL DESCRIPTION

configured in the Default_L2TPVPN IPSec VPN rule in the VPN > IPSec > IPSec
Setup screen. See Chapter 19 on page 205 for information on IPSec VPN.
IP Address Pool Enter the pool of IP addresses that the Device uses to assign to the L2TP VPN clients.
Note: These addresses use a 24-bit netmask and should not conflict with any WAN, LAN,
DMZ, WLAN, or PPTP VPN subnet even if they are not in use.
Access Group
(Optional)
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).
Authentication

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.
Keep Alive Timer 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.
