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.
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.
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 Name of the rule.
The Action that is applied on the traffic when the rule is valid.
Traffic blocked is indicated with a red cross, while traffic allowed with a green check mark.
The Source and Destination interface or IP address (range) to which the rule applies.
The protocol or Thomson Gateway Service (Any/ftp/dns...) for which the rule applies.
The number of Hits (number of times that the rule was applied to traffic).
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.
No panic: The Thomson Gateway itself is protected.
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.
Protocol checks will be performed on all accepted connections, irrespective of the chosen level.
