Does anyone have a guide to setting up a Firewall for an Ignition System?
It would be nice to have a central place (Knowledge Base article or other) that has
- all default ports for Ignition features listed with
- what functionality they are for, and
- where to find the setting in Ignition to either confirm or change.
I guess not. Here is one I made. Let me know if I missed anything.

Ignition’s native Ethernet/IP support only uses TCP port 44818. My Ethernet/IP Suite uses the full set. While you may need to open ports between different LAN segments within a plant, these ports (and similar) should never be opened to the outside world.

True. The WAN I mention in the guide is for multi-site systems that have a VPN WAN. Those ports are open for site to site connections, but not to the WWW. I’ll have to clarify that.
MQTT & MQTT Sparkplug_B ports at 1883
It's also worth noting that since the original post in 2017, we have released a port reference as part of our standard documentation. You can find it in the user manual.
