Nothing I can do about it, sorry.

Get a real ipv6 address, I can't do miracles.

DS-Lite means that you only got a IPv6 address for yourself by your provider.
The IPv4 address you get is only a pseudo address and shared with many other ISP customers.
This IPv4 address the ISP gives you is a address of one of their intern routers.
And they provide all the data through a DS-Lite tunnel using IPv6 to your router at home.
This means, port forwarding is not possible. Your computer can't be reached in the internet via IPv4.

I had a little argument with my ISP support. They told me, every ISP is switching to IPv6.
It seems to be true, I recherched a little.
Many big ISPs in Germany (for example KabelDeutschland, Telekom) only give IPv6 addresses to new customers.
And you probably heard, that all the internet addresses will switched to IPv6 in future.
And because the switching to IPv6 world wide just started, the ISPs additionaly provide DS-Lite for a pseudo IPv4 address.

So changing my ISP won't help anything because all the other ISPs do the same.
Not only in Germany, this must be world wide.
My ISP support told me that even Xbox services started to use IPv6.
And the developers of programs, games and hardware have to make sure, that their service is working on IPv6.

Dear Ze_Pilot, I know you already are a bit annoyed by me, but I keep posting, because it is important for the future of FAF.

Port forwarding is not possible with IPv6 and DS-Lite. And in future, there won't be any ISPs who give you a IPv4 addresses anymore!
It means, that I will not be the last (and probably not be the first) player with this kind of problem.
So it seems games who don't use IPv6 will die out if I got it right.

I'm not an IT expert, but I have the fear, that there is a big problem coming for FAF ...

I found a website where DS-Lite is explained a bit better: http://www.networkworld.com/community/node/46600

Can't do anything about providers wanting to do everything they want against peer to peer. (I don't see any other explanation why they do that).

Best course of action is to change to another provider that does not take you for a dummy. Never heard of DS-Lite, it's just a fancy name for "restricted connections - no p2p allowed".

I got some news.

At first, I contacted my router manufacturer.
They said the problem is my connection, not the router.
I am connected via DS-Lite.
That means, not only my router does NAT, my ISP does it again, too.
So my router forwards the FA data onto the right port, but my ISP forwards it to another, wrong port in their network after that.
Due to this, my router is not accessable via IPv4 from the Internet.

After that, I contacted my ISP. They told me that IPv4-connections without DS-Lite are only for premium customers.
For all others, only IPv6-connections are without any restrictions.

So I guess I can't do anything. Maybe that is the reason, why your proxy isn't working correctly, too?

But I wonder why I am the only one with this kind of problem. There must be some other players with DS-Lite, too.
What are you (the FAF developers) going to do, when more and more players will have DS-Lite due to the fact,
that IPv4-addresses are getting rarely and some other ISPs will do the same?
Is it possible to connect to other players in FA by using IPv6?

I hope you understand what I mean, it's quite confusing to me...

Whats this? "Ausnahmefehler aufgetreten" means something like "exception error occurred".

Means that windows tried to send the uPnP command, but it failed for some reasons.

You don't. You need a "modem". Most of the providers give it with a router integrated (most of the time a crappy one), but the router is not needed in most of the cases.

I have an ADSL 2 modem connected to the WAN port of my router, and my router can't connect directly to the "internet".

Thanks a lot, it made some things clearer to me.

Just one thing confuses me even more - as far as I knew, you need a router to get internet access for your network ... but whatever, that's not the topic.

I am going to make a support request to the routers manufacturer (AVM) now. But I'm sure they will argue it is FAF's fault, using a wrong port. But let's see...

Just some clarifications about what is doing what, because I think you are confused :
- Your router doesn't open port. It forward WAN ports to some PC ports.
- Your firewall close ports.
- A program open ports.

For FA to work :

- FA opens a port on your PC.
- Your firewall (in your pc or between your PC and your router) doesn't block that port your PC or LAN.
- Your router is forwarding FA data to your PC on that port.
- Your firewall (after or in your router) doesn't block the WAN port used by the router.

Opening a port is a program starting to listen on that port.
Forwarding is sending a packet from the internet to the correct PC/program waiting for these data.
If you only have a single PC on your network, you doesn't need any router, because there is nothing to route.

Mhh, I posted the symptomatics in posting #1 (look at "case 2"). I will post the game.log when it happens the next time.

Something weird: I opened UDP ports 10000-65535 (highest) now.
I started FAF, disabled using UPNP in the FAF settings and joined a game. In the logfile it now said "port used 56323". So it should have been open.
But i still got the message that i could not connect to some players ... it's freaking me out ...

By the way: the line "faf.fa.relayer UDP relay port [port] UDP relay port [port] never appears in the logfile. Is that something interesting for you?

You probably need to report that properly, it shouldn't happen.

Yeah that proxy is a great idea, but im losing connection to one or more players during the game!

By the way, i am a bit confused by this now: "In this case, the port is 55490. It means that your router is routing the port 55490 to your local port 6112.
Normally, the port used should be 6112. The fact that the router has opened a different port can be a potential problem, ... " (quoting wiki)

- Are you sure my router does open a different port? When using UPNP, in the list of ports opened due to UPNP, only the port selected in the FAF settings shows up.
The port which you can find in the faf.log does not show up in the list in my router configuration. It looks more like just FA is using a wrong port.

You have probably have one of these crappy router than add the last bit of your IP to the port you want to open. Can't do much about it.

Use the proxy server, it's made for that.

Re: Can't connect to most players

I tested a lot other ports. Even for example 19216, which my router chose itself. Didn't help.

And i did not try UPNP and port forwarding at the same time, you can be sure.

Let me explain it again to make it clear. I was using UPNP.
In FAF, i set the game port 19216, which was the last my router chose itself (and clicked on use UPNP).
Additionaly, my router opened port 19216 via UPNP.

Then I restarted FAF, joined a game and left again. That pop-up-window said that i could'nt connect to all 5 of 5 players (uh...).
When i looked at faf.log after that, there was written "INFO faf.client port used : 19324".
So there is nothing to wonder about why i wasn't able to connect.

As long I understand it correctly, the main problem is that my router is always choosing another port but not that one i want it to choose.
And because of UPNP my router should open that other port immediately, too, right?
But it's not doing that! It only opens the port I told it to use, not the one it is using de-facto!

Try another port than 6112. If uPnP is not working, something is wrong elsewhere.

Also, don't try port forwarding and uPnP at the same time, it won't work.
