VPN Tunnels
Applicable Version: 10.6.1 onwards
Overview
Setting a default Idle Timeout for any IPSec VPN Connection enables administrator to define the
maximum time for which the tunnel will stay connected even if no traffic passes through. This can be
done by setting a default Idle session time interval while configuring an IPSec Tunnel.
This article describes how we can set default Idle Timeout for IPSec VPN tunnels in Cyberoam.
Scenario
Set the default Idle Timeout as 500 seconds for a Site to Site VPN Connection named Head_Branch.
As a result, the VPN Tunnel will disconnect automatically if no traffic passes through the tunnel for the
specified time interval.
Configuration
You must be logged on to the Web Admin Console as an administrator with Read-Write permission for
relevant feature(s).


Go to VPN > IPSec > Connections and select the required Connection, for example,
Head_Branch.
Expand the Advanced Settings section and enable Disconnect when tunnel is idle. Set Idle
session time interval to 500.
