MH4U English Demo Online Multiplayer connection error

Yesterday I downloaded the MH4U demo from the Nintendo store, played solo for a bit, and then tried to set up a hunt with a friend online.

I created a Hall to hunt Tetsucabra, added a passcode, and sent my friend the Hall ID.

  • Is the Nintendo 3DS region-locked?
  • How can I watch 3DS Nintendo Video from another country?
  • Is it possible to take screenshots on the 3DS?
  • Bought a used 3DS, can I change the Nintendo ID and keep downloaded games?
  • Can I transfer 3DS stuff from one SD card to another?
  • Why won't this NPC move in?
  • When he tried to join, it asked him for the passcode, accepted it, and after that he said it threw an error.
    So we reversed the process; he created a Hall and I tried to connect. Same deal.
    Error 006-0612, please try again later.

    As per the Nintendo support link, we tried changing our 3DS’ DNS settings to Google DNS on the off chance that helped. We tried the same thing (I created a hall and he tried to connect, then vice-versa) and got the same result.

    Then I found a Chinese post that I do not fully understand, but seems to suggest setting your 3DS to your router’s DMZ. I cannot do this, as the 3DS requires that it have a static IP when set to the DMZ, while my router requires than any device set to the DMZ have a dynamic IP.

    Anyone else know where to go from here? Aside from buying a better router.

  • How big is a 3DS storage 'block'?
  • How to scan QR codes with a Nintendo 3DS?
  • Can I keep downloaded games on a 3ds XL after a system delete?
  • Do I keep pre-installed games when transferring from one 3DS to another?
  • What are Special Miis?
  • Are some glitches corrected on the virtual console version of old games like Pokemon red/blue/yellow

    To the poor souls with a Technicolour TG582n modem/router (or similar)

    1. Your modem/router requires a device to have a dynamically (DHCP) assigned address in order to use the DMZ
    2. Your 3DS appears to need a static address to access the internet when using the DMZ
    3. 1 and 2 contradict each other.

    The most obvious solution is to get a new modem/router.

    If you have a spare router with no modem functionality, you could also try setting your modem/router up in bridge mode to your spare router and then using the DMZ functionality on that one instead.

    Note that to set up bridge mode with a TG582n, you will need to use Telnet and the command line interface. Not recommended if you don’t know what those are, attempt at your own risk, YMMV, &c, &c. Less terrible modem/routers often let you easily configure bridge mode through the web interface, but then again, less terrible modem/routers probably either just work with MH4U or at least don’t require a dynamic addressed device for the DMZ.

    To anyone else

    1. The issue could be on the other end (e.g. if you get the error joining a game, it could be caused by a problem on your end or a problem on the host’s end).
    2. Check your modem/router’s firewall.
    3. Look up your modem/router’s DMZ settings and how to use them. This will be somewhat specific to each model. If it works with devices that have statically assigned IPs, try assigning your 3DS a static IP and then setting that IP to the DMZ. Nintendo provides a guide for setting a static IP on your 3DS..

    I’ll try to add a list of modem/routers my friends and I have successfully played with. Bear in mind that other factors, like firewalls or weird ISP settings
