To configure session limits:
1. Select Security from the main menu and Firewall from the submenu. The LAN WAN Rules
screen displays.
2. Click the Session Limit tab. The Session Limits screen will display.
To enable session limits:
3. Click the Yes radio button under Do you want to enable Session Limit?
4. From the User Limit Parameter drop-down menu, define the maximum number of sessions
per IP either as a percentage of maximum sessions or as an absolute value.
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, the
limit is the maximum number of sessions allowed from a single source machine as a
percentage of the total connection capacity. (Session Limit is a machine-based value.)
Otherwise, when the User Limit Parameter is set to Number of Sessions, the limit is an
absolute value.

Note: Some protocols (such as FTP or RSTP) create two sessions per connection
which should be considered when configuring session limiting.
