Firewall Port Forwarding

[marshalleq]

Is there an existing issue for this?

Hi, this looks like the best docker image - thanks for that. I just wanted to check that you definitely have this working externally i.e. other people can connect to the server. Because while it works perfectly on a LAN, it is showing as closed ports via the internet. And this is set up just like any other - I am well versed in doing this - but still closed ports. I'm going to delete the firewall rules and start again just in case, but thought I'd check. So far, a mystery.

I know you'll agree it looks like a firewall issue, but just wanted to check.

Thanks.

What you expected to see, versus what you actually saw

Clients can connect over the internet

Logs from the container

Well, it's been an interesting evening. I found some other rules in the firewall for steam that I removed. Now the internet can connect to the dedicated server, but the LAN can't. There is no firewall in between the local PC and Dedicated server on the LAN.

The only thing I can think of is that the container is binding to one address at a time (however in reality it only has a local host address (not using bridged mode).

Or other possibility is that I've set the Server IP to be the internet address on the firewall - which according to your wiki is for "the server empty check ". Not sure what that is and if it should be left out. A bit confusing this one.

[cp-fabian-pittroff]

Hey, I didn't really check if the setup works in a LAN environment. I need to do some testing with that. Maybe you can try to connect directly with the localip:port.

The IP for the empty check is optional. It checks through the steam api, if anyone is currently connected to the server and if yes, skips the update. So it won't change anything on the server itself.

[cp-fabian-pittroff]

so tested it locally, with two different machines. I didn't change any firewall settings.

Could you try again and see if the direct connect works for you?

[kennywasafk]

Bizarre as it is, I can't seem to be able to connect to the server locally (or via internet for that matter) either. Trying the IP:PORT directly just closes the dialogue window and does nothing. I've tried a few different docker images at this point to no avail, starting to think it might be my fault, but I'm not quite sure where it would be going wrong. If I switch the ports to tcp I can reach them fine from my network, so I don't think it's a container or network issue. It almost seems like an issue with server ports themselves not listening on specified address.

For reference, my container is exactly as in your docker-compose example, just with differend PUID and PGID values.

Any help would be much appreciated!

[cp-fabian-pittroff]

Hey, the ports need to be udp. I think it really only needs one of them (27015), but my guess, would be a firewall issue. What setup are you running? Docker Desktop or linux with Docker Engine?

If it's linux, do you have a firewall active (ufw or something)? Did you change the ports in the compose somewhere?

[kennywasafk]

Hey! Thanks for the quick reply. I do realise the ports need to be UDP, I changed them to TCP for testing purposes to understand if I can reach the container at all (which I could).

I'm running it on a Synology machine, the OS is linux-based. Synology's OS, DSM, does have its own firewall but I have that disabled. The ports in the compose are the same as in your example, I did not change anything. It's as below:

      - "17777:17777/udp"
      - "27015:27015/udp"

I've ran a Minecraft and Project Zomboid servers on the machine before so I know my set up does block all UDP connections or anything silly like that.

Seeing as I'm having trouble with multiple docker images I was thinking maybe the latest update for the game broke something, is that possible? Are you able to get the server up and running on your side with the container without issues atm?

[cp-fabian-pittroff]

My server is up and running (Mornedhels). Could you post the docker logs, maybe there is something going on with the server itself.

[kennywasafk]

Sure! Here are the logs for the last few hours it's been up. Let me know if you want me to restart it and post the full logs.

[kennywasafk]

Well, as always in these cases, the problem was evidently not with the container. A friend of mine was able to connect, so I'm assuming this is something to do with my copy of the game. Never the less thank you very much for trying to help!

[cp-fabian-pittroff]

Sure no problem. For you it could be a NAT loopback issue or something. And maybe now it will show up under the friends category

[cp-fabian-pittroff]

Can't be reproduce. Closed due to inactivity.

[marshalleq]

Just to let you know, I think this is a bug in the game. I ended up buying an off the shelf server. Since I posted this I tried a number of containers, a windows host, and a number of configurations. The only way I could get it to work on both LAN and WAN was to route the LAN through the firewall via NAT reflection. One thing that is consistent, is that even then, it was not consistent. And on the purchased online server, often the server still does not show up in the list. None of us have any idea exactly why, except that we are all certain it is a game server bug. I have logged a ticket with rocketwerkz I would suggest anyone having problems votes on one of the existing tickets there - there are lots. https://icarus.featureupvote.com/search?q=dedicated&page=1

[marshalleq]

so tested it locally, with two different machines. I didn't change any firewall settings.

Could you try again and see if the direct connect works for you?

When you tested this, do you have a router with some kind of NAT reflection? As that would work. I have not seen any evidence of it working without a router connecting local clients via the external IP instead of the internal IP so far.

[cp-fabian-pittroff]

I tested it again and now I can't see it on the LAN tab. So connecting without proper firewall rules and without NAT reflection will not work. I'm pretty sure, it worked on the local network without forwarding any port a few weeks ago.

Thanks for the update and I hope they gonna fix that soon.

[marshalleq]

Yes, that was actually my first problem. That it was working locally but not remotely. It 'feels like' it binds to the first subnet and sticks to that but clearly that's not the whole story when you consider that NAT is already communicating with the local subnet. Also, even if running via bay reflection, there are still similar problems where one of you cant find the server in the server list. Clearly there are a few bugs to work out. Hopefully they sort them out soon!

[compumark]

I have the same issue. I have setup an Icarus server with that image here on my Synology Docker container, I see the server on the LAN tab and the Internet tab and I can join locally. I have opened the 27015 UDP and 17777 UDP port in the firewall but the server is not listed and no one can connect via "Direct connect" Other servers locally eg. valheim and minecraft are working, so a firewall issue I would not take into concideration.

[cp-fabian-pittroff]

Hey @compumark, the direct connect is a little bit confusing in icarus. It seems the sever has to be in the public list to work. And you have to use the server port for it to work not the query port (so eg. 17777).

Best bet is to find the server with steam server browser and add it to favorites and connect through that. Could you tell me the server name, so I could check if I can find it?
