| DESCRIPTION |
Access |
| This field displays whether the firewall silently discards packets (deny), discards |
|
| packets and sends a TCP reset packet to the sender (reject) or permits the |
|
| passage of packets (allow). |
|
|
|
Log |
| This field shows you whether a log (and alert) is created when packets match this |
|
| rule or not. |
|
|
|
Add icon |
| Click the Add icon in the heading row to add a new first entry. |
|
| The Active icon displays whether the rule is enabled or not. Click it to activate or |
|
| deactivate the rule. Make sure you click Apply to save and apply the change. |
|
| Click the Edit icon to go to the screen where you can edit the rule on the ZyWALL. |
|
| Click the Add icon in an entry to add a rule below the current entry. |
|
| Click the Remove icon to delete an existing rule from the ZyWALL. A window |
|
| displays asking you to confirm that you want to delete the rule. Note that |
|
| subsequent firewall rules move up by one when you take this action. |
|
| In a numbered list, click the Move to N icon to display a field to type an index |
|
| number for where you want to put that rule and press [ENTER] to move the rule to |
|
| the number that you typed. For example, if you type 6, the rule you are moving |
|
| becomes number 6 and the previous rule 6 (if there is one) gets pushed up (or |
|
| down) one. |
|
| The ordering of your rules is important as they are applied in order of their |
|
| numbering. |
