Add a Rule to an Interface
3. Under Configuration, click Add Rule.
The Rule Setting dialog box appears.
4. Configure the Rule settings according to the following table:
Note: If you do not configure the public and private masks correctly the
system will be affected. You must specify addresses that exist. For
example, if you configure an outbound rule, the Public IP address and
Public Mask are the translated addresses. These addresses must be
assigned or packets will be sent to a non-existent destination. For
inbound rules, the translated address is the Private Address and Mask.
5. Click Save.
6. When you finish adding rules, configure the Rule Order box in the Rule
Configuration screen for the interface.
Note: Configure the rule order from most specific to most general. For
example, a TCP rule for one port should come before a general rule for
all TCP traffic. IP rules should come last.
7. Press Tab to update the screen.
