Hi All,

First time post here. Did a few google searches, but was unable to find a fix for my issue. I've been hosting game servers for various indie games a while now, so I'm pretty familiar with a standard home port forward.
However, I've recently turned one of my own old PC's into a PFsense router/firewall. It's going alright, I've setup some NAT/Firewall rules to allow the UDP port for 34179 (Standard port) and I'm piping it through to my servers address, however, when I launch my game as a client/server (for testing, the idea is to have it headless), I'm told that the game cannot get my external IP address.
I've had my co-workers go over my NAT rules to make sure they're right. Am I missing a port, are any of you able to point me in the right direction. I can see in the logs it's getting my correct IP address.

EDIT:

So after I posted this - I realised I was using both IPv6 and v4 on my pfsense WAN interface. I stopped this, because lets face it, Ipv6 blows and I was able to launch the game without the error. I had setup a DMZ to allow everything (which I turned off) and setup the NAT/Firewall rules. Now when I try to host, I'm getting 0.0.0.0:34197 on the Best Guest... Anymore idea?

Hello kaizo!

since you added an edit, did you edit the log file as well? i can't determine.
i know little of what you are talking about, but since you changed ip settings, might it be that the server file is configured for another ip address than the ip that is actually assigned?

what leads me to think this is the following:
180.181.116.99:34197 for best guess, but an answer to 139.162.150.14:34197.
this ip address leads to factorio itsself while it should be your own external ip adress (atleast it is on my server).

Hi Friendo,

Thanks for responding!

I did not, it's virtually the same log file, however please see below for change:

NewLogFile

More specifically, I believe this is the issue:

More Spec

I know now the issue is with my firewall, but I'm not sure where. It seems it's jumbling the ports for some reason, but I don't know of any features. I did read someone else on the forums had similar issues, but they solved it by resetting their modem/router, which I've done.

Forgive me, I don't quite get what you mean. Are you saying the Answer should be from my IP address and not the unknown 139 addy?

Further to all of this, I should mention users can direct connect to my public address and on my lan. It just won't talk with the factorio matchmaking system I guess.
I will also note that my config.ini, located in my appdata, port setting is 34197.
This is actually all a precursor, I do want to host a debian linux box and host a headless server, but I'd like to get my rules running on my windows machine, with GUI for easy troubleshooting at the moment.

Hello!

I fixed it. Apparently there is this super cool feature that randomises ports on PFsense, and other routers/firewall systems, that screw certain applications up. Things like VPN and such, which also extends to games.

I created an Outbound NAT rule, which keeps my server on a static port map, meaning if I'm sending out a packet with port 34179, it keeps the source/destination the same. Wow such a headache, but I guess I learned something new! Hopefully if anyone else has issues with PFsense/Randomising ports, this long winder tripple post from a man bashing his skull against the wall will help!

Happy factorio-ing! Hope to see you on my server soon

@@@@@@@@@

Wow, okay so my server is listed in the Public server list but people cannot connect. ;_________; Connection refused by server or some such. But I've had enough for today

shouldn;t it be port 34197? maybe its the nat rules.
maybe you made a typo there too

Hi,

Thanks for your responses. No, default configs. It was the port randomisation causing issues. My rules are correct and the server is now up and running. I forgot to update the post though. The people couldn't connect, because if you're behind a firewall, using NAT, you need to local connect via lan. Those outside of my network can connect fine. I've got a dynamic IP address, so my next step is loading a auto updating DNS, which appears to be working also.

Thanks again for your help, I'll mark the thread as soived!

As a fellow pfSense user, this had me grinding my teeth for an hour or so. Finally found this thread and fixed the outbound NAT.

Completely fixed the issue, thanks for posting about it and helping others out.

For what it's worth you need to turn on Hybrid Outbound NAT on the outbound NAT tab (Firewall / NAT / Outbound) for the static mapped port to work. Screenshot of how I have it set up below (do step 1 then 2):

it's not problem of factorio, but NAT/firewall.

2022 update, had the exact same issue after moving my router to pfsense.

I have a double NAT situation where my homeserver is under a guest network created by my ISP modem. I set up port forwarding for 34197 on the modem and pfsense, confirmed in Factorio I could connect to my server via my public IP, guest IP, and home server IP, but still the pingpong server was failing in the factorio server logs. Finally got it working properly thanks to the screenshots in this thread by setting up the Outbound NAT rule in pfsense

Thanks to everything that put this info together!

Do you have the outbound NAT type set to Hybrid? If it's Automatic (the default) then it won't work correctly. The 34197 NAT should be the only one you need - that's all I have and it works correctly, and it looks correct based on your first screenshot. You've included the screenshot for a second port (34198? For a second server?) that seems to be doing something where it keeps the interface IP instead of using the WAN address (you do want to use the WAN address though).

I believe on OPNsense you need to go to Firewall --> NAT --> Outbound to see the setting.
