Packet Filter
Packet filter, a firewall security measure, examines incoming and outgoing packet headers (IP address, port number, etc.) of the network and determines whether to forward the packets or not, based on user-defined rules (deny, accept and count). The CT-5241 SHDSL router provides packet filter and stateful packet inspection. It has denial of service protection against attacks such as ICMP Flood, Ping of Death, IP spoofing, Port Scans, Land Attacks, Tear Drop Attacks, IP Source Route and WinNuke Attacks. To access the packet filter functions, select Packet Filter from the advanced menu. The screen will display as below, showing a list of the currently configured filter entries.
Add a Packet Filter entry
To add a Packet Filter, complete the following steps: STEP 1: Enter values for the parameters (explained below). STEP 2: Click the Apply button at the bottom of the page. Priority You can enter a number here to assign the priority of a filter, in case there are overlapping rules. The lower the number the higher its priority.

This field determines the action the router will take when it receives a packet that corresponds to a filtering rule. It can be set to allow, to let the packet pass through the filter deny, to drop the packet count, which has no effect on whether the packet will be allowed through the filter, causes the packet to be included in the accounting statistics kept by the filter.

Interface

You can choose to apply this setting to a specific LAN or ATM interface. This function is called Packet Binding. Packet Binding is a function that can be used when we have multiple Virtual Channels (VC) and we are utilizing IP Packet Filtering. In some cases, we may not wish to apply the packet filtering to all VCs. In this case, we can bind IP packet filtering to a VC. This means that filtering will only be applied to the bound VC, and thus the remaining VCs will not filter packets.

Direction

This field determines whether the rule applies to Inbound, outbound or both directions
