7.3 Deﬁnition of Custom Traﬃc Rules

Figure 7.13 Traﬃc rule — setting a service

Use the Remove button to remove all items deﬁned (the Nothing value will be displayed in

the item list). Whenever at least one service is added, the Nothing value will be removed

automatically. If the Nothing value is kept in the Service column, the rule is disabled.

The Nothing value is important for removal of services (see chapter 14.3). The Nothing value

is automatically used for the Service item of rules where a removed service 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: If there is a protocol inspector for a certain service in WinRoute, it is applied to all corre-

sponding traﬃc automatically. If desired to bypass the protocol inspector for certain traﬃc,

it is necessary to deﬁne this exception in the particular traﬃc rule. For detailed information,

see chapter

7.7.

Action

Action that will be taken by WinRoute when a given packet has passed all the conditions for the

rule (the conditions are deﬁned by the Source, Destination and Service items). The following

actions can be taken:

• Permit — traﬃc will be allowed by the ﬁrewall

• Deny — client will be informed that access to the address or port is denied. The client

will be warned promptly, however, it is informed that the traﬃc is blocked by ﬁrewall.

• Drop — all packets that ﬁt this rule will be dropped by ﬁrewall. The client will not

be sent any notiﬁcation and will consider the action as a network outage. The action

is not repeated immediately by the client (the client expects a response and tries to

connect later, etc.).

Note: It is recommended to use the Deny option to limit the Internet access for local users and

the Drop option to block access from the Internet.
