Timer Section

A Timer Section is used to configure the various event timers used by racoon.



Configuration Example



In our configuration example, we define the timer section as shown below:


#

# Timer Section

#


timer

{

    natt_keepalive 15 seconds;

}

Timer section from our example racoon.conf configuration file.


NAT Traversal Keep Alive


A NAT Traversal keep alive value can be specified to enable keep alive packets. The value specifies how long racoon should wait between sending the packets. A keep alive packet is used to prevent a firewall or router from expiring a NAT state entry that is being used by a VPN Client. NAT state entries are typically expired when no matching packets have been seen during a configured time interval. If a NAT state expires, the Client could experience communications failure.
