The tunnel clients automatically handle the sorts of connection interruptions that users (and especially mobile
users) are familiar with, like undocking a laptop and taking it into a meeting or crossing cellular network
boundaries while on the road. Users can experience these temporary interruptions and then resume their
sessions without having to reauthenticate.
To allow sessions to be reestablished automatically when a user’s IP address changes (for example, when
moving from the office to home), select the Allow user to resume session from multiple IP addresses checkbox
when you set up EPC zones. See the steps described in Creating a Device Zone or Configuring the Default Zone for more information.
Reauthentication is, however, required if this setting is disabled or if any of the following is true:
- The user’s session on the appliance has expired
- The credentials provided (such as a SmartCard) do not persist during suspend/resume
