• If Fixed is selected, Personal Level Encryption will be used to scramble
the data using a fixed key.
• If PLE is selected, Personal Level Encryption will be used to scramble
the data using a key generated from the encryption secret.
• If DES56 is selected, the DES algorithm will be used. DES provides
better security than PLE, but also requires more time to compute.
• If 3DES is selected, the Triple DES algorithm will be used. In Triple
DES, the data is processed three times, each time with a different 56-bit
key.
v Note: PLE, DES56 and 3DES all require that an Encryption Secret be
configured for each user in the VPN Users dialog box. Some VPN devices
may not allow 3DES as an option.

> Start IP Address
The Start IP Address specifies the first IP address to be assigned to client
sessions under this configuration. This start address will be incremented by
one for each new client session, until the Max Connections limit (specified
using the General Tab) is reached. The IP address is freed when the client is
finished.
