It is important to realize that the set of installed VPN Gateways you are
running in a cluster are cooperating to give you a single system view.
Thus, when performing a minor or a major release upgrade, you only

The upgrade will automatically be executed on all the VPN Gateways in
operation at the time of the upgrade. All configuration data is retained. For
a minor upgrade, normal operations are usually unaffected, whereas a
major upgrade may cause the VPN Gateway to reboot.
Access to the Management IP address can be accomplished through
a Telnet connection or SSH (Secure Shell) connection. Note however
that Telnet and SSH connections to the VPN Gateway are disabled by
default, after the initial setup has been performed. For more information
