UMS Contacting the Download Server to Check for New Updates

The Universal Firmware Update feature is relevant for IGEL OS 11 devices and earlier, not for IGEL OS 12 devices.

The UMS initiates a TCP connection to port 443 at fwus.igel.com. The IGEL download server will send an answer containing a list of download links that enable the UMS to download the desired firmware.

Direct Connection

The following figure illustrates the communication between the UMS server and the IGEL download servers:

Via Proxy

When a proxy is positioned between the UMS and the IGEL download servers, the port on which the proxy is listening must be specified under UMS Administration > Global Configuration > Proxy Server.
