Chapter 5 Configuring the Router’s Security

To configure advanced filtering rules, click Add next to the rule title. The “Add Advanced Filter” screen appears.

To add an advanced filtering rule, define the following rule parameters:

Matching

To apply a firewall rule, a match must be made between IP addresses or ranges and ports. Use the “Source Address” and “Destination Address” drop-down lists to define the coupling of source and destination traffic. Port matching will be defined when selecting protocols. For example, if the FTP protocol is selected, port 21 will be checked for matching traffic flow between the defined source and destination IPs.

Operation

This is where the action the rule will take is defined. Select one of the following radio buttons:

•Drop - Deny access to packets that match the source and destination IP addresses and protocol ports defined in “Matching.”

•Reject - Deny access to packets that match the source and destination IP addresses and protocol ports defined in upper section of the screen, and send an ICMP error or a TCP reset to the origination peer.
