The Serv-U Gateway

The Serv-U Gateway provides defense in depth to Serv-U File Server deployments.

It acts as a reverse proxy in demilitarized zone (DMZ) segments and prevents your Serv-U File Server deployments from storing data in the DMZ, or opening connections from the DMZ to the internal network.

This type of architecture is essential to meet Payment Card Industry Data Security Standard (PCI DSS), managed file transfer, and other high-security requirements.

Gateway deployment documentation

The Gateway tab

The Gateway page in Server Details displays all configured gateways known to the Serv-U File Server deployment. Serv-U File Server periodically checks every configured gateway and displays a status message here.

Gateway Address column

The gateway address is the IP address on the Gateway that Serv-U File Server uses to communicate with Gateway. This should almost always be a private IP address.

A status icon is displayed on the left of the gateway address. The Status column displays a brief message that indicates the current status of the gateway.

The icon in the Gateway Address column changes to reflect the current gateway status.

Icon Description
The gateway is ready for connections. However, the gateway still needs listeners to receive connections.
Serv-U is checking the status of the gateway. Another status will appear in a few seconds.
The gateway is ready but the Serv-U installation is running close to the end of the trial period, or support period.
An error occurred. For more information about why it is not possible connect to the gateway, select the gateway entry, and select Properties.

Public IP Address column

The Public IP Address column shows the IP address file transfer clients should connect to.

A private IP address is displayed in the Public IP Address column if a private IP address was explicitly configured in the gateway. This occurs if the gateway has no public IP addresses, which is common during trials and situations in which the gateway is placed behind network address translation (NAT).

Description column

The Description column displays any note that is added to the gateway configuration. It does not affect behavior.

Manage Gateways

Click Add, Edit, or Delete to manage Gateway configurations.

  • Gateway Address is the IP address on the Gateway that Serv-U File Server uses to communicate with Gateway. This should almost always be a private IP address.
  • Port is the TCP port on the Gateway that Serv-U File Server uses to communicate with Gateway. The default is TCP port 1180.
  • Public IP Address should contain the IP address file transfer clients should connect to. A private IP address should be entered in the Public IP Address field if the gateway has no public IP addresses. This is common during trials and situations in which the gateway is behind NAT (network address translation).
  • The Enable Gateway option is used to turn the gateway on and off. The default is selected.
  • Description is an optional note about the gateway. It has no effect on the behavior.

Gateway properties dialog

Click Properties to view a detailed status about and add licenses to existing gateway configurations. This button only displays complete properties when Serv-U File Server is connected to the gateway.

Status

The large icon in the Status area and a status message indicate if the gateway is running, and whether or not it is running with a trial or commercial license.

The Available Public IP Addresses field contains a list of all the public IP addresses automatically detected on Gateway. If a private address is configured in the Public IP Address field of the gateway, this field displays a message indicating that no public IP addresses are found on the gateway server. This is expected behavior.

Install Information

The Install Information area shows the version and build date of the Gateway software running on the gateway, the date Gateway was installed or last updated, and, if applicable, the number of days left in the evaluation period.

Registration ID

Copy and paste your Gateway Registration ID (not your Serv-U File Server Registration ID) into this field, and click Save to apply a commercial license to your Gateway software.

If you have lost your registration ID, visit the Online Customer Service Center to retrieve it.
