SpeedTouch™ Web Interface
4.5.10 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.
