The Services settings that are available by navigating to Config | Network | Services are used to define the ports that will be used to access the web services hosted on the Apache server located on Untangle NGFW, such as the Administration interface, Spam Quarantine, Reports, and Blockpages.

By default, ports 80 and 443 are used to access these services. TCP traffic directed to the primary address of each interface on the HTTPS port will be forwarded to the local web server to provide services. So, when you have an internal service that needs to run on the default HTTPS port, you'll have to change the Untangle NGFW Services port, or add an alias IP to the interface and port forward the traffic directed to the alias IP to the internal service.

For example, if we set the new HTTPS port to 4343, we will use https://172.16.1.1:4343/ to access the Untangle-03 administration console instead of the default https://172.16.1.1/.
