Cannot find local game on LAN - Docker on UnRAID

I cannot find a local game on LAN using Docker in UnRAID. I can connect via IP address. not typically a problem, but I need to simplify this for my kids.

I have a bit of a unique setup. I have an UnRAID server that is my NAS and my backup solution for the house. It has the ability to run Docker containers, and as such I'm using your repository

I can successfully connect to this game server correctly through the IP Address, and it appropriately plays the correct save, and everything else. Problem is, that I just don't see it in the LAN list. I run vanilla, with one QoL mod, teleportation. linkmod:teleportation Any help would be appreciated! Edit: I do have Visibility over Lan enabled.

Try using host networking. https://github.com/dtandersen/docker_factorio_server/issues/88

This didn't work. I still can connect to the server through IP and port, but it doesn't show up in the LAN list... When I've used the full client to host a game, it has shown up in the LAN list, so not sure what I'm missing at this point.

I run mine on an unraid server also. Works just fine for me, I can find my game in Public and the LAN Menus.

My Container settings: (see image)

Well... Those are the same settings I have on the container... What about in the configs section? Anything unique in server-settings?

I think you need to add a password for access to the server:

"game_password": "set me",

here is mine with usernames and passwords changed.

I'll leave this open for a bit for troubleshooting, but I don't think anything needs to change on this end.

[jrhamilt]

I appreciate you leaving it open. I tend to agree, it's likely not on your end. I've tried making it public, and adding the password. Neither thing worked.

I do notice that I have trouble with my hostname on this (and other linux servers) propagating in my network. Don't know if that's related from a broadcast perspective, but if they are related, perhaps solving one solves all?

[TrueOsiris]

This is a consequence of how docker works and unraid firewalling. I was also forced to publish the factorio hosts on the public server (with passwords), because I did not want to mess with iptables on the unraid host. You could, besides a bridged network, add an extra network to the docker container, like macvlan, and add a route on the unraid host. I however, would recommend against that, because of security.

[SuperSandro2000]

I think changing the network mode to host should resolve this issue.

[j9ac9k]

I come from the google search results; had the same issue, but instead of needing to be set to "host" networking, I had to set a custom bridge option (which I noticed was one of the network devices).

Thanks for maintaining this docker image!
