Example 4 – SSH Sentinel Accessing LAN Through the RouteFinder
Multi-Tech Systems, Inc. RF760VPN/RF660VPN/RF600VPN Setup Examples Reference Guide (S000283D) 38
The IKE protocol does automatic negotiation of protocols, encryption algorithms; it keys automatic
exchange of keys. The following parameters must be set.
a) Connection name
Enter a text name that will identify the connection for you. For this example, enter Sentinel.
b) Compression
Do not check for this example.
c) Perfect Forward Secrecy (PFS)
Check the PFS checkbox to enable PFS, a concept in which the newly generated keys are
unrelated to the older keys). This is enabled by default.
d) Authentication Method
Check the Secret authentication method.
e) Secret
Since the authentication method is Secret, this field must be configured. The Secret must be
agreed upon and shared by the VPN endpoints; it must be configured at both endpoints of the
tunnel.
f) Select Encryption
Select the 3DES encryption method for this example.
g) IKE Life Time
The duration for which the ISAKMP SA should last is from successful negotiation to expiration. The
default value is 3600 seconds and the maximum is 28800 seconds.
h) Key Life
The duration for which the IPSec SA should last is from successful negotiation to expiration. The
default value is 28800 seconds and the maximum is 86400 seconds.
i) Number of Retries (Zero for Unlimited)
Enter of the number of retries you want the device to make in order to establish the connection.
Use zero for unlimited retries.
j) Local WAN IP
This is the interface initiating the IPSec tunnel. For this example, select WAN.
k) Local LAN
Local security gateway for which the security services should be provided. Select LAN.
l) Remote Gateway IP or FQDN
Interface where the IPSec tunnel ends. If you use a Dynamic IP address, this should be configured
to ANY. If you use a Static IP Address, then set to IP=Sentinel Client.
m) Remote LAN
Remote security gateway for which the security services should be provided. If the remote end is
the host, this should be configured as None.
n) UID (Unique Identifier String)
It is recommended that you accept the default to disable UID.
Note: When enabled, UID is used for compatibility purposes (other IPSec VPN gateways might
require you to input a Local and Remote IPSec Identifier).
o) Local ID
Do not set for this example.
p) Remote ID
Do not set for this example.
q) NetBIOS Broadcast
Do not set for this example.
