The Ignition web server runs on the 8088 port by default, but you can easily change it from the Gateway Control Utility (GCU). You may want to change the default port because the 8088 port is already being used by another application, or maybe you just want to use a more user-friendly port, such as 80.

To change the port

Here is how you can change the port:

  1. Launch Gateway Control Utility (GCU).
    Note that you can't change the port from the Gateway Configure section.
  2. In the lower-left side of GCU, type a different number for Port and SSL Port
    For example, type 80 for Port and 443 for SSL Port.
  3. Click Save.
    The Ignition Gateway will restart. If the port is already in use, Ignition will not start properly. You can go back to GCU and choose another port for the server. 
  4. Go to any webpage and if you have set Port to 80, type Localhost instead of Localhost:8088 to bring up Gateway.

If using Linux, be aware that ports under 1024 are considered Privileged Ports, and can't be bound to by non-root users. In these cases it's generally recommended to set up iptable rules to redirect packets from the privileged ports to non-privileged ports. 

Detailing how to do that is outside the scope of this user manual, but there are plenty of posts and discussions online on the subject
