Session Limit
This page allows you to specify total number sessions per user (IP) allowed across the router.
Session limiting is disabled by default. When enabling session limiting you can give  the maximum number of sessions per IP either in percentage of maximum sessions or absolute number of maximum sessions. If you want to give the  maximum number of sessions per IP in percentage check "yes" radio button otherwise check "No" radio button. The percentage is computed on the total connection capacity of the device. "User Limit" specifies the maximum number of sessions that should be allowed via router from a single source machine (i.e. session limiting is per machine based) as percentage of total connection capacity . Note that some protocols like ftp, rstp create two sessions per connection which should be considered when configuring session limiting. The label
"Total Number of Packets Dropped due to Session Limit:" shows total number of packets dropped when session limit is reached
