At this time this only works if your uisng IPv4. If your ISP is set up for IPv6 it most likely will not work for now. Thanks FistMaster & Warm Fuzzies for this info.

Messaggio originale di ColdGames:

I'm aiming to merge the co-op branch into experimental tonight. I can't guarantee I'll achieve this, but I'm currently on-track. Please try to be tolerant with technical issues. I'll try my best to assist players experiencing issues. Players wishing to host will need to port forward the steam port 27015 (you may already have this port forwarded for other games). Also please note that everything is a work in progress, so I'll be working though issues that players experience. I'll post once the build goes out. Thanks!

ColdGames is the man and is trying to get the update out soon but you might need to check a setting or two to be ready:

This port should be open already as it is required for steam use:

Required Ports for Steam
Which ports do I need to open on my router or firewall for Steam?
To log into Steam and download content:

------ > UDP 27015 through 27030 <-------
TCP 27015 through 27030

FYI - I had the test fail and it still worked. So if the test fails just try to host a game as it might work ;-)

Now let’s check if you are good to go. Anyone of these sites should tell you if you ready. Please know your IP address first:

https://support.microsoft.com/en-us/help/15291/windows-find-pc-ip-address

Or

Just type "what is my IP" in Google... lol :-)

Now go to one of the below sites:

http://www.portchecktool.com/
https://networkappers.com/tools/open-port-checker#.WdZctGhSyUk
http://canyouseeme.org/

If your test was successful your port is open :)

If not here is what you do it in windows 10 (older windows down below):
Source: http://www.tomshardware.com/faq/id-3114787/open-firewall-ports-windows.html

Open firewall ports in Windows 10

You can manually permit a program to access the internet by opening a firewall port. You will need to know what port it uses and the protocol to make this work.

1. Navigate to Control Panel, System and Security and Windows Firewall.
2. Select Advanced settings and highlight Inbound Rules in the left pane.
3. Right click Inbound Rules and select New Rule.
4. Add the port you need ---> 27015 <-----to open and click Next.
5. Add the protocol UDP and the port number into the next window and click Next.
6. Select Allow the connection in the next window and hit Next.
7. Select the network type as you see fit and click Next.
8. Name the rule something meaningful and click Finish.

You have now opened a firewall port in Windows 10!

Messaggio originale di ColdGames:

@Warm Fuzzies, no you shouldn't need to forward 7777. The only one needed is the steam port 27015 UDP.

If you're port forwarding on your router/modem, make sure the IP you're forwarding to matches the ip of the computer you're hosting on. You can check this by running the Command Prompt and typing "ipconfig" on your hosting computer.

The internal ip will show as IPv4 Address, and will be something like this: 192.168.1.#

For older windows you can find the information here: https://www.solvps.com/blog/how-to-open-ports-on-windows-server-vps-or-dedicated-server/

You may need to make this change on your router and here is that info:

https://www.wikihow.com/Set-Up-Port-Forwarding-on-a-Router

_______________________________________________________________________


Please make sure you open the port/ports in your antivirus, windows firewall, windows defender, any peerblocker or add blocker software and router if you have them.

Ok now restart both your COMPUTER and ROUTER (just in case it's needed) then go back up and check to see if it works.

If all this did not work it might be your antivirus and you can look it up on their site or try here as it is where I have gone before in the past:

https://portforward.com/

________________________________________________________________________


(IF YOU’RE HAVING ISSUES YOU CAN TRY AND PORT FORWARD 27015-27030)

(OR YOU CAN TRY THESE 27014 - 27050 AS IT ALSO WORKED WHEN THE ABOVE DID NOT)

_______________________________________________________________________


IF ALL OF THIS FAILS YOU CAN TRY THE FOLLOWING:

--------------------------------- > DANGER WILL ROBINSON !!!! <-------------------------------------

Only for a few minutes you could do the following.

1) Turn off Windows firewall (and any antivirus firewall) on the computer

2) Turn off the router's firewall and try hosting the game.

Can we see your hosted game?

3) Turn on Windows firewall

Can we see your hosted game?

4) Turn on the router's firewall and turn off the windows firewall

Can we see your hosted game?

5) Turn on all the firewalls to protect your computer/network (MAYBE RUN A VIRUS SCAN TO BE SAFE)


This way you will know if it is the:

Modem/ISP/STEAM (With all firewalls off we can't see)

Computer (windows firewall on and we can't see)

Router (Router's firewall on we can't see)

This way we narrow it to one of them and can focus on getting it set up right.

I am happy this update is coming soon and will try and help CG answer your questions. I would rather he spend his time adding to the game ;-)

Sorry if it's hard to follow.... first time writing a guide.... I'm better on video.... (I think) ;-)

And that is exactly why co-op is currently in Experimental so that you can report issues and they can be fixed.

Messaggio originale di ColdGames:

@Venturai I'm glad you were able to get a game going. There is an issue that's causing only one game to ever show at a time. It's possibly something I need to configure on the steam side. I'll be working to get this fixed once I'm home from work later.

It's all good buddy. A gem of a game from a gem of a developer :D

Messaggio originale di taters and gravy:

To be honest there should be more options for MP, like being able to join via IP address and not just having to refresh hoping to find your friends server.

I think more options will come with time and is why it's on the experimental branch so we can help ColdGames work out the bugs and issues ;-)

I think so too.

i did all of that but my friend still cannot find my server can someone contact me to help me about this on skype or teamspeak!

Good news CG fixed the issue and we can now see more than one hosted game. Let me know if your still having issues✌

Hey Critical could you help a bit ? i did all as it is in your guide and my friend and I still cant find eachothers games. when I host he cnat see me and vice versa

You mean, he hits refresh on the join multiplayer screen and he can't see your game in the list? And vice-versa? Has your friend followed the guide also?

If you both disable your Windows firewalls, can you then see each other? While it might help narrow down the cause, leaving your firewall disabled obviously isn't recommended. For what it's worth, I also added port 27015 Subsistence outbound rules to my Windows 10 firewall (not just inbound). One for TCP and one for UDP.

It's a great game and, when it didn't work for my wife and I at first, there isn't anything I wouldn't have tried. The 'invite through Steam' thing never worked, but now when I host she has no problem seeing the game in the list.

Hope this helps mate :)

We eaven tryed both disabling firewall still nothing

Messaggio originale di YellowLolly:

You know it's not the firewall then, so it has to be either your router settings or his. You've definitely opened that 27015 port, and your friend has too?

https://portforward.com/router.htm is the place to go mate, the descriptions are usually pretty well up to date for most routers.

I agree if you both disabled your windows firewall then it is the router or possibly the ISP that is the issue.

Nwm guys thx for help gonna play diffrent game till this is fixed... :) gl

[00 Critical]

If you are having issues you can try and port forward 27015-27030 as this did work for one person to be able to host. Thank Tibbs for this info ;-)

[Tabbs]

when you do your port forwarding should look like this:-

Local IP 192.172.0.1 (this is an example you need to put your IP in there)

Local start port 27015

local end port 27030

External start port 27015

External end port 27030

protocol choose both (in the list)

Enabled on (in the list)

From the link that 00 Critical linked that goes to Steam's support page for port forwarding, it includes port 27000, 27015, and 27030.

I wonder if there is a reason for not simply forwarding a range of 27000 to 27030. It eliminates the need for a bunch of separate forwards. I did that on mine, and it works fine. Granted, not sure if steam even uses any of the ports between 27001 and 27014.

Did the same as an inbound and outbound exception for my firewall.

Of note, my firewall already had a self generated entry for subsistence for inbound. I assume that is for downloading updates.


When the co-op first hit experimental, I even went so far as to create a blanket exception for both inbound and outbound, that forwarded ALL ports in my firewall and router.

That didnt actually work, so im not convinced that the issues people are having with it are port related.

Me, I blame Steam. It's always Steam's fault.
