WWW Overview
The following figure shows secure and insecure management of the UAG coming in from the WAN.
HTTPS and SSH access are secure. HTTP and Telnet access are not secure.
Note: To allow the UAG to be accessed from a specified computer using a service, make
sure you do not have a service control rule or to-Device security policy to block
that traffic.
• See
To-Device Rules on page 290
for more on To-Device security policies.
To stop a service from accessing the UAG, clear
Enable
in the corresponding service screen.
46.7.1
Service Access Limitations
A service cannot be used to access the UAG when:
1
You have disabled that service in the corresponding screen.
2
The allowed IP address (address object) in the
Service Control
table does not match the client IP
address (the UAG disallows the session).
3
The IP address (address object) in the
Service Control
table is not in the allowed zone or the

Each user is also forced to log in the UAG for authentication again when the reauthentication time
expires.
You can change the timeout settings in the
