Configuration Example - Allowing Access Requests from IP Addresses in a Specified Region

Assume that domain name www.example.com has been connected to WAF and you want to allow only IP addresses in Ireland to access the domain name. Perform the following steps:

1. Add a geolocation access control rule: Select Ireland for Geolocation and select Allow for Protective Action.
   Figure 2 Selecting Allow for Protective Action
   

2. Enable geolocation access control.
   Figure 3 Geolocation Access Control configuration area
   

3. Configure a precise protection rule to block all requests.
   Figure 4 Blocking all access requests
   

   For details, see Configuring Custom Precise Protection Rules.

4. Clear the browser cache and access http://www.example.com.

   When an access request from IP addresses outside Ireland accesses the page, WAF blocks the access request.

5. Go to the WAF console. In the navigation pane on the left, choose Events. View the event on the Events page. You will see that all requests not from Ireland have been blocked.

Configuration Example - Blocking Access Requests from IP Addresses in a Specified Region

Assume that domain name www.example.com has been connected to WAF and you want to block all IP addresses from Ireland to access the domain name. The following shows how to configure a rule to this end:

1. Add a geolocation access control rule, select Ireland for Geolocation and Block for Protective Action.

2. Enable geolocation access control.
   Figure 7 Geolocation Access Control configuration area
   

3. Clear the browser cache and access http://www.example.com.

   When an access request from IP addresses inside Ireland accesses the page, WAF blocks the access request.

Protection Effect

To verify WAF is protecting your website (www.example.com) against a rule:

1. Clear the browser cache and enter the domain name in the address bar to check whether the website is accessible.
   • If the website is inaccessible, connect the website domain name to WAF by referring to Website Settings.
   • If the website is accessible, go to 2.

2. Add a geolocation access control rule by referring to Configuring a Geolocation Access Control Rule.
3. Clear the browser cache and access http://www.example.com. Normally, WAF blocks such requests and returns the block page.
4. Return to the WAF console. In the navigation pane, click Events. On the displayed page, view the event log.
