Packet Filter > Packet Filter Rules

Packet filters are used to set firewall rules which define what type of data traffic is allowed across the RouteFinder's firewall. There are certain System Defined Rules that exist by default. In addition, you can specify whether particular packets are to be forwarded through the RouteFinder system or filtered. These rules are set with the help of network/host and service definitions that have already been set up in the Networks section.

Screen Notes:

This screen applies to the RF820/RF820-AP and RF830/RF830-AP.

The RF830/RF830-AP screen includes an option for a WAN2Interface.

If the AP build is used, WLAN displays in the System defined rules.

Show Packet Filter Rules in Popup Window

Clicking this button opens up a new window that displays the RouteFinder’s live packet filter rules.

System Defined Rules

These rules define a set of common application services that are allowed outbound access through the RouteFinder's WAN interface. The services that come under this definition FTP, TELNET, SMTP, DNS, HTTP, POP3, IMAP, and HTTPS; they form the Default Outbound Service Group. The Default Outbound Service Group is enabled by default.

Add User Defined Packet Filter Rules

New packet filter rules are created by choosing from four drop-down lists. All services, networks, and groups previously defined in Networks and Services are available for selection.

Click Add to create the rule; it then displays at the bottom of the table. The new rule automatically receives the next available number in the table. The overall effectiveness of the rule is decided by its position in the table. You can move the new rule within the table with the Move function in the Command column. You can also Edit and Delete rules.
