Option Description
PPP Address Range
(Start/End)
Configure the dedicated IP address pool for L2TP/PPTP. The
LAN IP subnet at one end of the VPN tunnel must be different
from the LAN
IP subnet at the other end of the VPN tunnel. For example, if
one side’s LAN subnet is 192.168.0.x, then the other side
should be 192.168.1.x (where the subnet mask in this
example is 255.255.255.0).
Select Enable to enable MPPE (Microsoft Point-to-Point
Encryption). MPPE is used to enhance the confidentiality of
