Controlling Traffic Based on DNS and Network

Network conditions in DNS rules allow you to control traffic by its source IP address. You can explicitly specify the source IP addresses for the traffic you want to control.

Procedure

Step 1

In the DNS rule editor, click Networks.

Step 2

Find and select the networks you want to add from the Available Networks, as follows:

  • To add a network object on the fly, which you can then add to the condition, click Add (add icon) above the Available Networks list and proceed as described in Creating Network Objects.

  • To search for network objects to add, click the Search by name or value prompt above the Available Networks list, then type an object name or the value of one of the object’s components. The list updates as you type to display matching objects.

Step 3

Click Add to Source, or drag and drop.

Step 4

Add any source IP addresses or address blocks that you want to specify manually. Click the Enter an IP address prompt below the Source Networks list; then type an IP address or address block and click Add.

Step 5

Save or continue editing the rule.
