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
Remote 840 Manager”
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.
