An example Capture Rule

​Let's look at an example for creating a rule to capture traffic originating from specific IP addresses.

1. Add a condition for Source Address
2. In the value field enter the IPs you want captured. Sample valid syntax is provided in the image:
   • Multiple values are always comma-separated with no spaces
   • The first value (highlighted green) shows how to specify a range
   • The second value (highlighted yellow) shows a single IP value
   • The third value (highlighted blue) shows CIDR notation for entire IP subnets
3. Set the Action Type to "Capture"
4. Click Done to finalize the rule
