of addresses on your local network.
• Client Netmask: Enter the IP address of the netmask used for SSL VPN
clients. The Client Address Pool is used with the Client Netmask. If they are
set as follows, then the SSL VPN client will get a VPN address whose range
is from 10.0.0.1 to 10.0.0.254.
- Client Address Pool = 10.0.0.0
- Client Netmask = 255.255.255.0
• Client Domain: Enter the domain name used for the SSL VPN clients.

a configurable login banner is displayed. Enter the message text to display
along with the banner.

• Idle Timeout: Enter the timeout value in seconds that the SSL VPN session
can remain idle.
• Session Timeout: Enter the timeout value in seconds that a SSL VPN
session can remain connected.
• Client DPD Timeout: Dead Peer Detection (DPD) allows detection of dead
peers. Enter the DPD timeout for client in this field.
• Gateway DPD Timeout: Enter the DPD timeout for SSL VPN gateway in this
field.
• Keep Alive: If you want the SSL VPN server to keep sending a message at
an interval, enter the value of interval in this field.
• Lease Duration: Enter the amount of time after which the SSL VPN client
must send an IP address lease renewal request to the server.
• Max MTU: Enter the maximum transmission unit for the session.
• Rekey Method: Specify the session rekey method (SSL or New Tunnel).
Rekey allows the SSL keys to be renegotiated after the session has been
established.
• Rekey Interval: Enter the frequency of the rekey in this field.
