If You Inadvertently Deny IP Access to All Hosts
If you select Deny by Default in Port restrictions - Allow/Deny by IP address section from Port Configure Global IP Access Settings tab, all hosts are restricted from accessing the server ports. Hence, API Gateway cannot communicate with Integration Server.
For example, if you have defined five ports and those ports are configured to use the global IP access settings. In such case, if you change the global IP access setting to Deny By Default, API Gateway cannot communicate with hosts through any ports.
This section explains the steps to reset your setting and allow API Gateway to communicate with Integration Server.
To modify the global IP access settings
1. Log off from API Gateway.
2. Open the diagnostic port of the Integration Server by entering http://hostname:diagnostic port in your browser's address bar.
For example, 10.2.100.112:9999. By default, the diagnostic port is 9999.
3. Navigate to the Security > Ports.
The Port List appears.
4. Perform any of the following:
Click
Allow in the
IP Access column of the required port.
5. Restart Integration Server.
6. Refresh your browser and log on to API Gateway and modify global IP access settings.
