Chapter 6 Traffic Policy

1.If you require authentication for any rule, it is necessary to ensure that a rule exists to allow users to connect to the firewall authentication page. If users use each various hosts to connect from, IP addresses of all these hosts must be con- sidered.

2.If user accounts or groups are used as a source in the Internet access rule, auto- matic redirection to the authentication page nor NTLM authentication will work. Redirection requires successful establishment of connection to the destination server.

If traffic policy is set like this, users must be told to open the authentication page (see chapters 9 and 8.1) in their browser and login before they are let into the Internet.

This issue is described in detail in chapter 23.5.

Firewall — a special address group including all interfaces of the host where the firewall is running. This option can be used for example to permit traffic between the local network and the WinRoute host.

Use the Any button to replace all defined items with the Any item (this item is also used by default for all new rules). This item will be removed automatically when at least one new item is added.

Use the Remove button to remove all items defined (the Nothing value will be displayed in the item list). Whenever at least one item is added, the Nothing value will be removed automatically. If the Nothing value is kept for the Source or/and Destination item, a cor- responding rule is disabled.

The Nothing value takes effect when network interfaces (see chapter 5.1) and users or groups (see chapter 13) are removed . The Nothing value is automatically used for all Source or/and Destination items of rules where a removed interface (or user or a group) has been used. Thus, all these rules are disabled. Inserting the Nothing value manually is not meaningful —a checking box in the Name column can be used instead.

Note: Removed interfaces cannot be replaced by the Any value, otherwise the traffic policy might be changed fundamentally (e.g. an undesirable traffic might be allowed).

Service

Definition of service(s) on which the traffic rule will be applied. Any number of services defined either in Configurations Definitions Services (see chapter 12.3) or using protocol and port number (or by port range — a dash is used to specify the range) can be included in the list.
