Allowing only specific traffic to the local subnet

You can create a firewall rule that permits only specific traffic to your local subnet. This firewall rule always applies to your local subnet IP address, regardless of what the address is. Therefore, even if you change your local subnet IP address, you never have to modify this rule for the new address.

For example, you can create this rule to permit traffic to port 80 only on the local subnet, regardless of what the local subnet IP address is.

To allow only specific traffic to the local subnet

  1. In the console, open a Firewall policy.

  2. On the Firewall Policy page, click Rules.

  3. On the Rules tab, in the Rules list, select the rule that you want to edit.

  4. In the Firewall Rules table, in the Host column, double-click on the rule for which you want to create a local subnet traffic condition.

  5. Under the type of hosts for which this rule applies (Local or Remote), click Add.

  6. Click the Address Type drop-down list and select Local Subnet.

  7. Click OK, and then click OK again to close out of the Host List dialog box.
