STEP 11 In the Log field, specify whether or not the packets for this rule should be logged.

may generate a significant volume of log messages and is recommended for

Restricting Sessions
You can limit the maximum number of unidentified sessions and half-open
sessions on the Cisco RV 120W. You can also introduce timeouts for TCP and UDP
sessions to ensure Internet traffic is not deviating from expectations in your private
network.
To configure session settings:
STEP 1 Choose Firewall > Session Settings.
STEP 2 In the Maximum Unidentified Sessions field, enter the maximum number of
unidentified sessions for the ALG identification process. This value can range from
2 through 128. The default is 32 sessions.
STEP 3 In the Maximum Half Open Sessions field, enter the maximum number of half-open
sessions. A half-open session is the session state between receipt of a SYN
packet and the SYN/ACK packet. Under normal circumstances, a session is
allowed to remain in the half-open state for 10 seconds. The maximum value
ranges from 0 through 3,000. The default is 128 sessions.
STEP 4 In the TCP Session Timeout Duration field, enter the time, in seconds, after which
inactive TCP sessions are removed from the session table. Most TCP sessions
terminate normally when the RST or FIN flags are detected. This value ranges from
0 through 4,294,967 seconds. The default is 1,800 seconds (30 minutes).
