If the status icon in DMZ Gateway does not change color from red to green, indicating a successful connection, verify the following:
Verify the services for both EFT Server and DMZ Gateway are started. (Look in the Services dialog box in the Windows Control Panel or the Task Manager.)
If you make changes in DMZ Gateway, make sure to click Apply. If necessary, stop and then restart the service after making changes.
Verify the IP address for EFT Server is not blocked in DMZ Gateway's IP Access Exception list. By default all IP addresses are granted access until you block or allow specific addresses. (Refer to Installing and Configuring DMZ Gateway for the procedure for blocking/unblocking IP addresses.)
Verify EFT Server can reach the IP address that DMZ Gateway is listening on.
If you made configuration changes in EFT Server, especially connection settings (protocols allowed, ports, etc.), make sure to stop and then restart the EFT Server service. Once restarted, make sure EFT Server is running (listening for new connections) and that the Gateway remains enabled.
Verify the DMZ Gateway settings in EFT Server have the proper IP address and port for the gateway and that the allowed protocols and ports have been defined for allowed incoming client connections to DMZ Gateway.
If a connection between EFT Server and DMZ Gateway is indicated, but clients cannot connect to EFT Server through the Gateway, check the following:
Verify that you can connect to EFT Server using a client account from within your network.
If successful, it indicates something is not configured properly in the DMZ Gateway settings, either in DMZ Gateway or in EFT Server. Verify that EFT Server and DMZ Gateway are connected (see above) and that, in the EFT Server Gateway configuration settings, the correct protocols and ports are specified for incoming client connections to the gateway. These are the ports on which external clients will connect to the gateway. If no protocol is enabled or the wrong port is defined, clients will not be able to connect to the gateway.
If it fails, then it is a configuration issue in EFT Server. Review your configuration of user accounts and connection settings.
