Firewall for your Internet connection turned off
Your network is not protected against hackers making unauthorised access from the
Internet. The section entitled "Firewall" on page 79 describes how to avoid this secu-
rity risk.
u
Address translation for your Internet connection turned off
The clients in your network are not protected against unauthorised access from the
Internet. The section entitled "Setting up the NAT function" on page 88 describes
how to avoid this security risk.
u
One or more of your local clients directly exposed to the Internet
One or more clients in your network are directly visible to the Internet as exposed
hosts and therefore particularly exposed to risk (e.g. from hacker attacks). You
should only activate this function if it is absolutely necessary (e.g. to operate a Web
server) and other functions (e.g. port forwarding) are not adequate. In this case you
should take appropriate measures on the clients concerned. The section entitled
"Opening the firewall for selected PCs (Exposed Host)" on page 92 describes how to
avoid this security risk.
u
Remote management enabled
Any user, including unauthorised ones, who gains knowledge of the system pass-
word for your device can access your device's configuration program via the Inter-
net. The section entitled "Setting up Remote Management" on page 120 describes
how to avoid this security risk.
