Reference Guide for the Model RT328 and Model RH348 ISDN Routers

Filter Configuration

For incoming packets, the router applies data ﬁlters only. Packets are processed depending on
whether a match is made. The router allows you to customize the ﬁlter sets that you want to use.
The following sections describe how to conﬁgure the ﬁlter sets for the router.

Router Filter Structure

You can conﬁgure up to 12 ﬁlter sets, each with up to six rules. For IP packets, these rules involve
comparing the protocol type of a data packet (for example, TCP, UDP), source or destination
addresses, or port numbers. Also, a generic ﬁlter may be deﬁned to merely test for a byte or pattern
of bytes in a particular location in the packet. When a rule is met (or not met), a user-speciﬁed
action is taken. This action may be to forward the packet, drop the packet, or go to the next rule.

When implementing these ﬁlter sets, you can link up to four of the ﬁlter sets together to screen
the data packet. Therefore, with each ﬁlter set having up to six rules, you can have a maximum
of 24 rules active for a single ﬁltering application.

Configuring a Filter Set

To conﬁgure a ﬁlter set, select option 21 in the Main Menu. This selection brings up Menu 21 -
Filter Set Conﬁguration. From this menu, you can choose from among 12 ﬁlter sets. Select the
ﬁlter that you want to conﬁgure or choose an unused set to create a new ﬁlter. In order to
distinguish between the 12 ﬁlter sets, each ﬁlter set should have a name or some comments. When
you select a set for editing, you will be prompted to provide some descriptive text to be displayed
in the comment ﬁeld of Menu 21 next to the ﬁlter number.

When you have ﬁnished ﬁlling in the Edit Comments ﬁeld, press [Enter] at the Press ENTER to
Conﬁrm... prompt to conﬁrm your selections, or press [Esc] at any time to cancel your selections.
The new information will now be displayed in the read-only section of Menu 21 - Filter Set
Conﬁguration.
