Working with Firewall Tunneling

Important:

Tunneling is not available for MS Windows OS.

Tunneling provides a means to establish a persistent connection between Zend Studio and a remote server situated behind a firewall or NAT. After a firewall tunnel is created, instead of assigning more communication ports for the Debug / Profile Sessions with the remote server, all communication between Zend Studio and the remote server proceeds through the tunnel.

Note for Windows OS users:

Tunneling does not work when Zend Server for IBMi is installed on a Windows-based server. However, you can perform remote debugging to a machine behind a firewall as long as the correct ports are open on both ends.

The tunnel communication port should be used in the following circumstances:

  1. When debugging or profiling files on a remote server which is behind a firewall or other security device.

  1. Establishing communication between Zend Studio and Zend Server for IBMi when Zend Server for IBMi is running on a remote server which is behind a firewall or other security device. The communication between Zend Studio and Zend Server for IBMi facilitates the integration of Zend Server for IBMi event reporting capabilities with Zend Studio’s editing, debugging and profiling features, and makes it more effective.

To set up a tunneling connection, several configuration settings must be defined, both in Zend Studio and on your server's debugger. This can be done through Zend Server for IBMi , Zend Platform, Zend Core or your php.ini file.
