Configuring Session Limits
To prevent one user or group from using excessive system resources, you can limit the total
number of IP sessions allowed through the VPN firewall for an individual or group. You can
specify the maximum number of sessions by either a percentage of maximum sessions or an
absolute number of maximum sessions. Session limiting is disabled by default.
To configure session limits:
1. Select Security > Firewall from the main/submenu.
2. Click the Session Limit tab. The Session Limit screen is displayed.
3. Click the Yes radio button under Do you want to enable Session Limit?
4. From the User Limit Parameter drop-down list, define the maximum number of sessions per
IP either as a percentage of maximum sessions or as an absolute.
The percentage is computed on the total connection capacity of the device.
5. Enter the User Limit. If the User Limit Parameter is set to Percentage of Max Sessions, this
is the maximum number of sessions allowed from a single source machine as a percentage of
the total connection capacity. (Session Limit is per machine based.) Otherwise, if the User
Limit Parameter is set to Number of Sessions, the user limit is an absolute value.
