Low:
All outgoing connections are allowed. All incoming connections are blocked,
except for ICMP (Internet Control Management Protocol) and 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.
BlockAll:
All traffic from and to the Internet is blocked. Game and Application Sharing is
not allowed by the firewall.
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.
