@steveits I tried that just to see if it would work for me, and it still would not allow a connection

@behemyth Sorry for being back so "late" but it sure works!

@jimp Yes, thank you, that's probably exactly it. It's been so long since I've upgraded that I completely forgot to reinstall updated drivers as I've done in the past.

@bob-dig said in [solved] UPnP behind double NAT is not working, even with a STUN-Server:

@jimp @viktor_g I now tested it with the google STUN Server and it is working for me.

Great! That's the same one I used when testing and it worked well here.

I guess the redmine Issue https://redmine.pfsense.org/issues/12797 could be closed too.

The problem I mentioned on the Redmine issue is still a legitimate issue that is being worked on. It affects new outbound connections (like for game clients) and not inbound connections like those for torrent/download clients.

@oldirtyjedi said in How about updating the pinned topics?:

@jimp Well, this is an interesting case.

Everything is fixed, by installing the new miniupnpd patch that is pinned at the top of the gaming subforum.

Yep, but I also did update that pinned post since the fix was discovered :-)

So, you are correct - but this is perhaps now added to pfSense and makes this appliance more consumer friendly?

Indeed.

In retrospect - this all just happened. But these pinned topics will need to be revised if this fix is added to pfSense in future builds. They are no longer valid.

With the exception of needing the patch, the other info is still valid. Some games and/or consoles do not support UPnP so they need static port oubound NAT. If games support UPnP that will need to be enabled+configured.

can be closed i deactivated uPnP and now steam works - lol

Just in case anyone else has this problem:
I reinstalled pfsense with the same settings and now it's working.

Thanks for your contribution!
i was inspired by this post and came to solution with every console with open nat and working play together

@radarg ok it looks like all the UPNP is working I see the rules pop up. Why would the second xbox try to talk to the same port at the first one? I thought that once the second xbox made contact with the server it would use a different port. Am I wrong?

To anyone got the same problem, don't tick Static port box in Outbound rule (other games may need it). It took me a few days trial and error XD
