# Allow traffic from specific countries only

This example [custom rule](https://developers.cloudflare.com/waf/custom-rules/create-dashboard/) blocks requests based on country code using the [ip.src.country](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/ip.src.country/) field, only allowing requests from two countries: United States and Mexico.

* **When incoming requests match**:

| Field   | Operator  | Value                 |
| ------- | --------- | --------------------- |
| Country | is not in | Mexico, United States |  
If you are using the expression editor:  
`(not ip.src.country in {"US" "MX"})`
* **Then take action**: _Block_
