VPN and Remote Access Setup
8-5
Maximum
MPPE This option indicates that the router will use the MPPE encryption
scheme with maximum bits (128 bits) to encrypt the data.
Mutual Authentication (PAP) :
The Mutual Authentication function is mainly used to communicate with
other routers or clients which need bidirectional authentication in order to
provide stronger security. For example, Cisco routers. That is, enable
it only if the connecting router requires mutual authentication. By default,
the option is set to No. Notice that if you enable the Mutual
Authentication function, you should further specify the Username and
Password for communication purpose.
Username Specify the username for the purpose of the Mutual
Authentication.
Password Specify the password for the purpose of the Mutual
Authentication.
IP Address Assignment for Dial-In Users :
Start IP
Address Enter a start IP address for the dial-in PPP connection. You
should choose an IP address from the local private network. For
example, if the local private network is
192.168.1.0/255.255.255.0, you could choose 192.168.1.200 to
be the Start IP Address.
8.2.3 IKE/IPSec General Setup
Set up a common Pre-shared key and security method for remote dial-in
user or non-specified node (LAN to LAN) which do not have fixed IP
address. This setup only applies to IPSec-related VPN connections. For
example, L2TP over IPSec and IPSec tunnel.
