Monster Hunter Freedom Unite (MHFU)

[Zed_Acid]

Hi folks, I just registered because everything that came up with searches was either really old (2+ years) or doesn't work.

Also, I need to preface this with a little more info than usual:

My ISP is really weird in that I already have IPv6, which makes me unable to port forward - I could force them to switch it to IPv4, but that then means my wife can't use the same line for some reason (I researched this rather extensively for another game a while back and came upon this constantly).

So now I can play MHFU with her with the latest "official" PPSSPP version.
1.3, I believe.

Everything works fine, I went and read up on the settings and whatnot, and after a few tweaks we can now easily and effortlessly connect in the Guild Hall and play with each other.

Now I have a friend in another town (not far away), and we use Tunngle for LAN games, and he also loves MH games so we play that, too.

It works flawlessly via Tunngle.

Only not when my wife comes into the picture.
We can all meet in the Guild Hall, even exchange items etc, but on quest, it's the old "Long Loading Time Then Wifey Breaks Off"

We tried everything we could think of, made triple sure the settings are the same on all three systems, Tunngle is working correctly, all three computers use Win 7 64, all three have the exact same PPSSPP version and MHFU version. Firewalls are off and in any case have all the proper permissions for PPSSPP even when on.

Another point that may be important is that only I can host - When we switch the IP's to either my wife's (Tunngle or my real LAN) or to the Tunngle IP of my friend, we can't even enter the Guild Hall (the new host can, but not the other two). In case of the LAN I can't enter my wife's Hall, I mean - Friend obviously can't anyway, this was just for testing.

Maybe a clue right there.

But we are at the end of our ropes, and I am sorry for that convoluted wall of text, but perhaps someone has an idea that would make 3 MH freaks who always loved the games but really really want to play together very happy.

To recap:
3 Computers, two in the same room, one in a town a few kilometers away.
All three use Win 7 64, latest stable PPSSPP, same MHFU version.
All settings according to forums' solutions.
Using Tunngle, all have different IP's.
Two way works, either me and wife or me and friend, but not three way. Only I can host for some reason.

Thanks for reading.

Edit: In case the port forward is an issue for some reason, we have in the past used Tunngle to connect us three and also more than us three in other games without issues, even when those games required port forwarding (which was the reason we turned to Tunngle in the first place)
