The server now shows in public browser, however, when attempting to connect through the public browser you will get an error, the server is available on the web and allows inbound connections when connecting to the ip directly. This is due to the fact the outbound ports are randomized and because the server needs to reach out to update the browser with connection details and keepalive state on port 34197.

This is better explained by this writeup on serverfault;

If anyone has any ideas on how we can look to resolve this I would be happy to implement them.

setting hostNetwork: true in the deployment spec results in the following error

MultiplayerManager failed: Host address is already in use.

removing node port from the chart allowed me to configure this option
however, it did not help.

ping is still not showing and we are not able to connect to the server.

firewall logs, everything looks to be routing fine and the ip is routable externally and can communicate back as per the logs.

The issue was related to a Nat rule not applying in the correct order. I was able to trace this down with the help of the factorio discord. Looking at the client log located in the appdata directory mentioned here
We were able to see that the client log was trying to connect to the appropriate public ip, and the rules were applied according to the documentation on the edgerouter hairpin Nat. However, the ultimate fix was that I had to move the rules to a random order save and then move them back. I assume this could have also been fixed by a reboot of the firewall but wasn't ideal to do at this time.

How about use https://github.com/ZCube/factorio-port-fixer.

According to https://www.factorio.com/blog/post/fff-143 it is the pingpong server that determines the initial port. Therefore, you can use the port you want by simply replacing that server. ( Currently port 34197 is fixed and port forwarding is required. )

It would be nice if hostAliases settings for pods were added.

It looks like could use my https://github.com/MOZGIII/port-map-operator to solve the issues with NAT in this particular case, and use the LoadBalancer service type.
