Thomson Gateway GUI
Security Levels
Following describes all of the predefined security levels:
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 by the Thomson Gateway.
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: (This is the default firewall level)
All in- and outgoing traffic is allowed to pass through your Thomson Gateway, including Game and
Application Sharing.
The firewall levels only have impact on traffic passing through your Thomson Gateway. This
means that the handling of traffic directly appointed from and to Thomson Gateway is independent
of the selected firewall level. The Thomson Gateway itself is always protected, even if you disable
the firewall.
Protocol checks will be performed on all accepted connections, irrespective of the chosen level.
It is not possible to deactivate the firewall completely via the GUI.
Security level settings
The Security Level Settings page displays the overview of the different firewall rules of the active security
level.
Under Firewall Settings, you can find following details:
The status of the firewall rule: either enabled or disabled.
