CONFIGURING FILTERS

Introduction

The OfficeConnect Remote 840 provides an extensive set of data filtering

 

capabilities. For instance, filters can accept packets only from specific

 

addresses to provide added security, or filters can be added to reduce

 

network traffic and improve overall performance.

 

This chapter contains information on the filtering capabilities for your

 

OfficeConnect Remote 840. It is divided into the following sections:

 

“Filtering Overview”

 

“Filtering Capabilities”

 

“Creating Filters Overview”

 

“Creating Filters Using the OfficeConnect Remote 840 Manager”

 

“Step-by-Step Guide to Creating Filters Using the OfficeConnect

Filtering Overview

Filters can provide added security by accepting packets only from specific

 

addresses or they can be added to reduce network traffic and improve

 

overall performance.

Packet filters control inter-network data transmission by accepting or rejecting the passage of specific packets through network interfaces based on packet header information. When data packets are received by a network interface such as an Ethernet LAN or WAN port, a packet filter analyzes packet header information against a set of rules you define. A filter then lets the packet pass through or discards it.
