Enter the domain name or Fixed IP address in the Address Data field.
You can set up multiple remote dynamic IP policies, but only one such policy can be
enabled at a time.
4.
Specify the Local LAN settings:
•
From the IP Address list, select Subnet address, Single address, or Range
address.
•
Fill in the Single/Start IP Address field.
•
If you are specifying a range, fill in the Finish IP Address field.
This range must be an address range used on your LAN. For a single IP address, do
not fill in the Finish IP Address field.
The remote VPN endpoint must have these IP addresses entered as its remote
addresses.
5.
Specify the Remote LAN settings.
•
From the IP Address list, select Single PC -no Subnet, Single address, Range
address, or Subnet address.
If there is no LAN (only a single computer) at the remote endpoint, select the Single
PC -no Subnet option. The Single address option is typically used to access a server
on the remote LAN.
•
If you want to specify a range, fill in the Finish IP Address field.
This range must be an address range used on the remote LAN.
•
Fill in the Subnet Mask field.
The remote VPN endpoint must have these IP addresses entered as its local addresses.
6.
Specify the ESP (Encapsulating Security Payload) settings:
ESP provides security for the payload (data) sent through the VPN tunnel.
•
In the SPI field, enter the required security policy indexes (SPIs).
Each policy has to have unique SPIs. These settings need to match the remote VPN
endpoint. The in setting here has to match the out setting on the remote VPN
endpoint, and the out setting here has to match the in setting on the remote VPN
endpoint.
•
From the Encryption list, select DES or 3DES, and fill in the Key field.
For 3DES, the keys should be 24 ASCII characters, and for DES, the keys should be
8 ASCII characters.
-
DES. The Data Encryption Standard (DES) processes input data that is 64 bits
wide, encrypting these values using a 56-bit key. Faster but less secure than
3DES.
-
3DES. (Triple DES) achieves a higher level of security by encrypting the data
three times using DES with three different, unrelated keys.
