Chapter 45 VPN/IPSec Setup
436
A
Y signifies that this VPN rule is active.
Local Addr 
Start
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Single, this is a 
static IP address on the LAN behind your Prestige.
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Range, this is 
the beginning (static) IP address, in a range of computers on the LAN behind your 
Prestige. 
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is 
a static IP address on the LAN behind your Prestige.
Addr End / 
Mask
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Single, this is 
the same (static) IP address as in the Local Addr Start field.
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Range, this is 
the end (static) IP address, in a range of computers on the LAN behind your Prestige. 
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is 
a subnet mask on the LAN behind your Prestige.
Encap
This field displays Tunnel mode or Transport mode. See earlier for a discussion of 
these. You need to finish configuring the VPN policy in menu 27.1.1.1 or 27.1.1.2 if ??? 
is displayed.
IPSec 
Algorithm
This field displays the security protocols used for an SA. ESP provides confidentiality 
and integrity of data by encrypting the data and encapsulating it into IP packets. 
Encryption methods include 56-bit DES and 168-bit 3DESNULL denotes a tunnel 
without encryption.168-bit 3DES and 128-bit AESNULL denotes a tunnel without 
encryption.
AH (Authentication Header) provides strong integrity and authentication by adding 
authentication information to IP packets. This authentication information is calculated 
using header and payload data in the IP packet. This provides an additional level of 
security. AH choices are MD5 (default  - 128 bits) and SHA -1(160 bits).
Both AH and ESP increase the Prestige’s processing requirements and 
communications latency (delay).
You need to finish configuring the VPN policy in menu 27.1.1.1 or 27.1.1.2 if ??? is 
displayed.
Key Mgt
This field displays the SA’s type of key management, (IKE or Manual).
Remote Addr 
Start
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Single, this is a 
static IP address on the network behind the remote IPSec router.
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Range, this is 
the beginning (static) IP address, in a range of computers on the network behind the 
remote IPSec router.
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is 
a static IP address on the network behind the remote IPSec router.
This field displays N/A when you configure the Secure Gateway Address field in SMT 
27.1.1 to 0.0.0.0.
Addr End / 
Mask
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Single, this is 
the same (static) IP address as in the Remote Addr Start field.
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to Range, this is 
the end (static) IP address, in a range of computers on the network behind the remote 
IPSec router. 
When the Addr Type field in Menu 27.1.1 IPSec Setup is configured to SUBNET, this is 
a subnet mask on the network behind the remote IPSec router.
This field displays N/A when you configure the Secure Gateway Address field in SMT 
27.1.1 to 0.0.0.0.
