6: Basic Parameters Port Range Action Generate rule to allow service Enter a range of destination TCP or UDP port numbers to be tested. An entry is required for TCP, TCP New, TCP Established, and UDP, and is not allowed for other protocols. Separate multiple ports with commas. Separate ranges of ports by colons. Examples: 22 - filter on port 22 only 23,64,80 - filter on ports 23, 64 and 80 23:64,80,143:150 - filter on ports 23 through 64, port 80 and ports 143 through 150 Select whether to Drop, Reject, or Allow communications for the specified IP address, subnet mask, protocol, and port range. Drop ignores the packet with no notification. Reject ignores the packet and sends back an error message. Allow permits the packet through the filter. You may wish to "punch holes" in your filter set for a particular protocol or service. For instance, if you have configured your NIS server and wish to create an opening in your filter set, select the NIS option and click the Add Rule button. This entry adds a new rule to your filter set using the NIS -configured IP address. Other services and protocols added automatically generate the necessary rule to allow their use. 3. Click the right arrow button to add the new rule to the bottom of the Rules list box on the right. A maximum of 64 rules can be created for each ruleset. 4. To remove a rule from the filter set, highlight that line and click the left arrow. The rule populates the rule definition fields, allowing you to make minor changes before reinserting the rule. To clear the definition fields, click the Clear button. 5. To change the order of priority of the rules in the list box, select the rule to move and use the up or down arrow buttons on the right side of the filter list box. 6. To save, click the Apply button. The new filter displays in the menu tree. Note: To add another new filter rule set, click the Back to IP Filter link to return to the Network > IP Filter page.
