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. |

Timeout values can also be configured with user defined values. The maximum value for timeout is 432000 seconds. |
TCP Timeout:
TCP traffic sessions(such as e-mail and data transfer) through the router can be bounded by a timeout value set in this field.
