This chapter shows you how to determine which services/protocols can access which ZyWALL / USG
zones (if any) from which computers.
Note: To access the ZyWALL / USG from a specified computer using a service, make sure
no service control rules or to-ZyWALL / USG firewall rules block that traffic.

52.1.2 System Timeout

There is a lease timeout for administrators. The ZyWALL / USG automatically logs you out if the

does not time out when a statistics screen is polling.
Each user is also forced to log in the ZyWALL / USG for authentication again when the
reauthentication time expires.
