5.5.13 Firewall
About the firewall
The firewall allows you to secure traffic from and to the SpeedTouch™. There are
different security levels, depending on the degree of security you need.
Overview
The
Overview
page summarizes the overall security policy configured on your
SpeedTouch™.
Configure
On the
Configure
page you can select the security level of the SpeedTouch™.
Security Levels
Select one of following security levels:
±
BlockAll
:
All traffic from and to the Internet is blocked. Game and Application Sharing is
not allowed by the firewall.
±
Standard
:
All outgoing connections are allowed. All incoming connections are blocked,
except for inbound connections assigned to a local host via Game and
Application Sharing.
±
Disabled
:
All in- and outgoing traffic is allowed to pass through your SpeedTouch™,
including Game and Application Sharing.
This is the default firewall level.
Although BlockAll should block all connections, some mandatory types
of traffic such as DNS will still be relayed between LAN and WAN via
the SpeedTouch™.
The firewall levels only have impact on the forward hook. This means that
the handling of traffic from and to the Web pages of the SpeedTouch™ is
independent of the selected firewall level.
Protocol checks will be performed on all accepted connections, irrespective
of the chosen level. You can only disable protocol checks via the CLI.
